The Hewlett-Packard Company, commonly shortened to Hewlett-Packard (/ˈhjuːlɪt ˈpækərd/ HYEW-lit PAK-ərd) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses (SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'".

The company won its first big contract in 1938 to provide the HP 200A, a low distortion frequency oscillator  for Walt Disney's production of the animated film Fantasia, which allowed Hewlett and Packard to formally establish the Hewlett-Packard Company on July 2, 1939. The company grew into a multinational corporation widely respected for its products. HP was the world's leading PC manufacturer from 2007 until the second quarter of 2013, when Lenovo moved ahead of HP. HP specialized in developing and manufacturing computing, data storage, and networking hardware; designing software; and delivering services. Major product lines included personal computing devices, enterprise and industry standard servers, related storage devices, networking products, software, and a range of printers and other imaging products. The company directly marketed its products to households; small- to medium-sized businesses and enterprises, as well as via online distribution; consumer-electronics and office-supply retailers; software partners; and major technology vendors. It also offered services and a consulting business for its products and partner products.

In 1999, HP spun off its electronic and bio-analytical test and measurement instruments business into Agilent Technologies; HP retained focus on its later products, including computers and printers. It merged with Compaq in 2002, and acquired Electronic Data Systems in 2008, which led to combined revenues of $118.4 billion that year and a Fortune 500 ranking of 9 in 2009. In November 2009, HP announced its acquisition of 3Com, and closed the deal on April 12, 2010. On April 28, 2010, HP announced its buyout of Palm, Inc. for $1.2 billion. On September 2, 2010, HP won its bidding war for 3PAR with a $33 a share offer ($2.07 billion), which Dell declined to match.

On November 1, 2015, the company spun off its enterprise products and services business Hewlett Packard Enterprise. HP retained the personal computer and printer businesses and was renamed HP Inc.

Bill Hewlett and David Packard graduated with degrees in electrical engineering from Stanford University in 1935. The company started in a garage in Palo Alto during a fellowship they had with past professor Frederick Terman at Stanford during the Great Depression, whom they considered a mentor in forming the company. In 1938, Packard and Hewlett began part-time work in a rented garage with an initial capital investment of US$538 (equivalent to $11,185 in 2022). In 1939, Hewlett and Packard decided to formalize their partnership. They tossed a coin to decide whether the company they founded would be called Hewlett-Packard (HP) or Packard-Hewlett.

Hewlett and Packard's first financially successful product was a precision audio oscillator known as the HP 200A, which used a small incandescent light bulb (known as a "pilot light") as a temperature dependent resistor in a critical portion of the circuit, and a negative feedback loop to stabilize the amplitude of the output sinusoidal waveform. This allowed the HP 200A to be sold for $89.40 when competitors were selling less stable oscillators for over $200. The 200 series of generators continued production until at least 1972 as the 200AB, still tube-based but improved in design through the years.

One of the company's earliest customers was Bud Hawkins, chief sound engineer for Walt Disney Studios, who bought eight HP 200B audio oscillators (at $71.50 each) to be used in the animated film Fantasia. HP's profit at the end of 1939, its first full year of business, was $1,563 on revenues of $5,369.

In 1942, they built their first building at 395 Page Mill Road and were awarded the Army-Navy "E" Award in 1943. HP employed 200 people and produced the audio oscillator, a wave analyzer, distortion analyzers, an audio-signal generator, and the Model 400A vacuum-tube voltmeter during the war.

Hewlett and Packard worked on counter-radar technology and artillery shell proximity fuzes during World War II; the work exempted Packard from the draft, but Hewlett had to serve as an officer in the Army Signal Corps after being called to active duty.

HP was incorporated on August 18, 1947, with Packard as president. Sales reached $5.5 million in 1951 with 215 employees. The company went public on November 6, 1957. In 1959, a manufacturing plant was established in Böblingen and a marketing organization in Geneva. Packard handed the presidency over to Hewlett when he became chairman in 1964, but remained CEO of the company.

1960s

The HP200A, a precision audio oscillator, was the company's very first financially successful product.

HP is recognized as the symbolic founder of Silicon Valley, though it did not actively investigate semiconductor devices until a few years after the "traitorous eight" abandoned William Shockley to create Fairchild Semiconductor in 1957. Hewlett-Packard's HP Associates division, established around 1960, developed semiconductor devices primarily for internal use. HP Associates was co-founded by another former Bell Labs researcher, MOSFET inventor Mohamed Atalla, who served as Director of Semiconductor Research. Instruments and calculators were some of the products using semiconductor devices from HP Associates.

During the 1960s, HP partnered with Sony and Yokogawa Electric in Japan to develop several high-quality products. The products were not a huge success, as there were high costs involved in building HP-looking products in Japan. In 1963, HP and Yokogawa formed the joint venture Yokogawa-Hewlett-Packard to market HP products in Japan. HP bought Yokogawa Electric's share of Hewlett-Packard Japan in 1999.

HP spun off the small company Dynac to specialize in digital equipment. The name was picked so that the HP logo could be turned upside down to be a reflected image of the logo of the new company. Dynac was eventually renamed Dymec and folded back into HP in 1959. HP experimented with using Digital Equipment Corporation (DEC) minicomputers with its instruments, but entered the computer market in 1966 with the HP 2100 / HP 1000 series of minicomputers after it decided that it would be easier to build another small design team than deal with DEC. The minicomputers had a simple accumulator-based design with two accumulator registers and, in the HP 1000 models, two index registers. The series was produced for 20 years in spite of several attempts to replace it, and was a forerunner of the HP 9800 and HP 250 series of desktop and business computers.

At the end of 1968, Packard handed over the duties of CEO to Hewlett to become United States Deputy Secretary of Defense in the incoming Nixon administration. He resumed the chairmanship in 1972 and served until 1993, but Hewlett remained the CEO.

1970s

The HP 3000 was an advanced stack-based design for a business computing server, later redesigned with RISC technology. The HP 2640 series of smart and intelligent terminals introduced forms-based interfaces to ASCII terminals, and also introduced screen labeled function keys, now commonly used on gas pumps and bank ATMs. The HP 2640 series included one of the first bit mapped graphics displays that, when combined with the HP 2100 21MX F-Series microcoded Scientific Instruction Set, enabled the first commercial WYSIWYG presentation program, BRUNO, that later became the program HP-Draw on the HP 3000. Although scoffed at in the formative days of computing, HP surpassed IBM as the world's largest technology vendor in terms of sales.

Introduced in 1968, "The new Hewlett-Packard 9100A personal computer is ready, willing, and able ... to relieve you of waiting to get on the big computer."

HP was identified by Wired magazine as the producer of the world's first device to be called a personal computer: the Hewlett-Packard 9100A, introduced in 1968. HP called it a desktop calculator because, as Hewlett said: "If we had called it a computer, it would have been rejected by our customers' computer gurus because it didn't look like an IBM. We therefore decided to call it a calculator, and all such nonsense disappeared." An engineering triumph at the time, the logic circuit was produced without any integrated circuits, and the CPU assembly was entirely executed in discrete components. With CRT display, magnetic-card storage, and printer, the price was around $5,000. The machine's keyboard was a cross between the keyboard of a scientific calculator and the keyboard of an adding machine. There was no alphabetic keyboard.

Apple co-founder Steve Wozniak originally designed the Apple I computer while working at HP and offered it to them under their right of first refusal to his work; they did not take it up as the company wanted to stay in scientific, business, and industrial markets. Wozniak said that HP "turned him down five times", but that his loyalty to HP made him hesitant to start Apple with Steve Jobs.

The company earned global respect for a variety of products. They introduced the world's first handheld scientific electronic calculator in 1972 (the HP-35), the first handheld programmable in 1974 (the HP-65), the first alphanumeric, programmable, expandable in 1979 (the HP-41C), and the first symbolic and graphing calculator, the HP-28C.

Like their scientific and business calculators, HP oscilloscopes, logic analyzers, and other measurement instruments had a reputation for sturdiness and usability. HP introduced the Hewlett-Packard Interface Bus (HPIB) computer peripheral interface (later cloned by National Instruments as GPIB and standardized by the IEEE as IEEE-488) on their relay actuator products in 1973; HPIB was later integrated into most high end test & measurement equipment it produced from 1980 onward. As early as 1977 HP began production of the HP856x spectrum analyzers to complement its RF power meters and sensors capable of measuring signals in excess of 20 GHz. HP also produced configurable chassis based sweep generators capable of generating signals to 20GHz. Other T&M products of the time included lab grade multimeters, microwave frequency counters, RF amplifiers, high accuracy microwave detectors, lab grade power supplies and more. These products were succeeded by modernized versions as well as the introduction of the scalar and vector network analyzer product lines prior to the business being spun off into Agilent Technologies.

The HP 9800 series of technical desktop computers started in 1971 with the 9810A. The HP series 80 started in 1979 with the 85. Some of these machines used a version of the BASIC programming language, which was available immediately after they were switched on, and used a proprietary magnetic tape for storage. HP computers were similar in capabilities to the much later IBM Personal Computer, though the limitations of available technology forced prices to be high.

In 1978, Hewlett stepped down as CEO and was succeeded by John A. Young.

HP expanded into South Africa in the 1980s. Activists supporting divestment from South Africa accused HP of "automating apartheid".

Sales reached $6.5 billion in 1985 with 85,000 employees.

In 1984, HP introduced both inkjet and laser printers for the desktop. Along with its scanner product line, the printers have later been developed into successful multifunction products, the most significant being single-unit printer/scanner/copier/fax machines. The print mechanisms in HP's LaserJet line of laser printers depend almost entirely on Canon Inc.'s components (print engines), which in turn use technology developed by Xerox. HP developed the hardware, firmware, and software to convert data into dots for printing.

On March 3, 1986, HP registered the HP.com domain name, making it the ninth Internet .com domain to be registered.

In 1987, the Palo Alto garage where Hewlett and Packard started their business was designated as a California Historical Landmark.

1990s

In the 1990s, HP expanded their computer product line, which initially had been targeted at university, research, and business users, to reach consumers. HP also grew through acquisitions: it bought Apollo Computer in 1989 and Convex Computer in 1995.

In 1992, Young was succeeded by Lewis E. Platt, and in 1993 and Hewlett and Packard stepped down from the board with Platt succeeding Packard as chairman.

In 1993, HP acquired Advanced Design System from Pathwave. The ADS suite of RF simulation tools was spun off into Agilent in 1999 along with related T&M business units, all of which were carried forward into the spinoff of Agilent into Keysight.

Later in the decade, HP opened hpshopping.com as an independent subsidiary to sell online, direct to consumers; in 2005, the store was renamed "HP Home & Home Office Store".

From 1995 to 1998, Hewlett-Packard were sponsors of the English football team Tottenham Hotspur.

In 1999, all of the businesses not related to computers, storage, and imaging were spun off from HP to form Agilent Technologies. Agilent's spin-off was the largest initial public offering in the history of Silicon Valley, and it created an $8 billion company with about 30,000 employees, manufacturing scientific instruments, semiconductors, optical networking devices, and electronic test equipment for telecom and wireless, research and development, and production.

In July 1999, HP appointed Carly Fiorina as the first female CEO of a Fortune-20 company in the Dow Jones Industrial Average. Fiorina received a larger signing offer than any of her predecessors. The same year, Fiorina articulated a set of "rules of the garage", an attempt to capture the spirit of the company's founders.

Sales to Iran despite sanctions

In 1997, HP started selling its products in Iran through a European subsidiary and a Dubai-based Middle Eastern distributor, despite U.S. export sanctions prohibiting such deals imposed by Bill Clinton's 1995 executive orders. The story was initially reported by The Boston Globe, and it triggered an inquiry by the U.S. Securities and Exchange Commission (SEC). HP responded that products worth US$120 million were sold in fiscal year 2008 for distribution via Redington Gulf, a company based in the Netherlands, and that as these sales took place through a foreign subsidiary, HP had not violated sanctions.

HP named Redington Gulf "Wholesaler of the Year" in 2003, which in turn published a press release stating that "[t]he seeds of the Redington-Hewlett-Packard relationship were sowed six years ago for one market — Iran." At the time, Redington Gulf had only three employees whose sole purpose was to sell HP products to the Iran market. According to former officials who worked on sanctions, HP used a loophole by routing their sales through a foreign subsidiary. HP ended its relationship with Redington Gulf after the SEC inquiry.

2000–2005

On September 3, 2001, HP announced that an agreement had been reached with Compaq to merge the two companies. In May 2002, after passing a shareholder vote, HP officially merged with Compaq. Prior to this, plans had been in place to consolidate the companies' product teams and product lines.

As Compaq took over Tandem Computers in 1997 and Digital Equipment Corporation in 1998, HP offers support for the former Tandem NonStop family and Digital Equipment products PDP-11, VAX and AlphaServer.

The merger occurred after a proxy fight with Bill Hewlett's son Walter, who objected to the merger. HP became a major producer in desktop computers, laptops, and servers for many different markets. After the merger with Compaq, the new ticker symbol became "HPQ", a combination of the two previous symbols, "HWP" and "CPQ", to show the significance of the alliance and also key letters from the two companies Hewlett-Packard and Compaq (the latter company being famous for its "Q" logo on all of its products).

In 2004, HP released the DV 1000 Series, including the HP Pavilion dv 1658 and 1040. In May 2006, HP began its campaign, "The Computer is Personal Again"; the campaign was designed to bring back the personal computer as a personal product. The campaign utilized viral marketing, sophisticated visuals, and its own website. Some of the ads featured Pharrell, Petra Nemcova, Mark Burnett, Mark Cuban, Alicia Keys, Jay-Z, Gwen Stefani, and Shaun White.

In January 2005, following years of underperformance, which included HP's Compaq merger that fell short and disappointing earning reports, the board asked Fiorina to resign as chair and chief executive officer of the company, and she did on February 9, 2005. After her departure, HP's stock jumped 6.9 percent. Robert Wayman, chief financial officer of HP, served as interim CEO while the board undertook a formal search for a replacement.

Mark Hurd of NCR Corporation was hired to take over as CEO and president, effective April 1, 2005. Hurd was the board's top choice given the revival of NCR that took place under his leadership.

2006–2009

In 2006, HP unveiled several new products including desktops, enhanced notebooks, a workstation, and software to manage them—OpenView Client Configuration Manager 2.0. In the same year, HP's share price skyrocketed due to consistent results in the last couple quarters of the year with Hurd's plan to cut back HP's workforce and lower costs.

In July 2007, HP signed a definitive agreement to acquire Opsware in a cash tender deal that values the company at $14.25 per share, which combined Opsware software with the Oracle enterprise IT management software.

In the first few years of Hurd's tenure as CEO, HP's stock price more than doubled. By the end of the 2007 fiscal year, HP reached the $100 billion mark for the first time. The company's annual revenue reached $104 billion, allowing HP to overtake competitor IBM.

On May 13, 2008, HP and Electronic Data Systems (EDS) announced that they had signed a definitive agreement under which HP would purchase EDS. On June 30, HP announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 had expired. "The transaction still requires EDS stockholder approval and regulatory clearance from the European Commission and other non-U.S. jurisdictions and is subject to the satisfaction or waiver of the other closing conditions specified in the merger agreement." The agreement was finalized on August 26, 2008, at $13 billion, and it was publicly announced that EDS would be re-branded. The first targeted layoff of 24,600 former EDS workers was announced on September 15, 2008. (The company's 2008 annual report gave the number as 24,700, to be completed by end of 2009.) This round was factored into purchase price as a $19.5 billion liability against goodwill. As of September 23, 2009, EDS was known as HP Enterprise Services (now known as DXC Technology).

On November 11, 2009, 3Com and Hewlett-Packard announced that the latter would be acquiring 3Com for $2.7 billion in cash. The acquisition was one of the biggest in size among a series of takeovers and acquisitions by technology giants to push their way to become one-stop shops. Since the beginning of the financial crisis in 2007, tech giants have constantly felt the pressure to expand beyond their current market niches. Dell purchased Perot Systems recently to invade into the technology consulting business area previously dominated by IBM. Hewlett-Packard's latest move marked its incursion into enterprise networking gear market dominated by Cisco.

2010–2012

On April 28, 2010, Palm, Inc. and HP announced that the latter would buy the former for $1.2 billion in cash and debt. Adding Palm handsets to the HP product line created some overlap with the iPAQ series of mobile devices, but was thought to significantly improve HP's mobile presence as iPAQ devices had not been selling well. Buying Palm, Inc. gave HP a library of valuable patents and the mobile operating platform, webOS. On July 1, 2010, the acquisition of Palm, Inc. was finalized. Purchasing its webOS was a big gamble to build HP's own ecosystem. On July 1, 2011, HP launched its first tablet, HP TouchPad, which brought webOS to tablet devices. On September 2, 2010, HP won the bidding war for 3PAR with a $33 a share offer ($2.07 billion) that Dell declined to match. After HP acquired Palm Inc., it phased out the Compaq brand.

On August 6, 2010, Hurd resigned amid controversy and CFO Cathie Lesjak assumed the role of interim CEO. Hurd had turned HP around and was widely regarded as one of Silicon Valley's star CEOs, and under his leadership, HP became the largest computer company in the world when measured by total revenue. He was accused of sexual harassment against a colleague, though the allegations were deemed baseless. The investigation led to questions concerning some of his private expenses and the lack of disclosure related to the friendship. Some observers have argued that Hurd was innocent, but the board asked for his resignation to avoid negative public relations. Public analysis was divided between those who saw it as a commendable tough action by HP in handling expenses irregularities, and those who saw it as an ill-advised, hasty, and expensive reaction in ousting a remarkably capable leader who had turned the business around. At HP, Hurd oversaw a series of acquisitions worth over $20 billion, which allowed the company to expand into services of networking equipment and smartphones. HP shares dropped by 8.4% in after-hours trading, hitting a 52-week low with $9 billion in market capitalization shaved off. Larry Ellison publicly attacked HP's board for Hurd's ousting, stating that the HP board had "made the worst personnel decision since the idiots on the Apple board fired Steve Jobs many years ago".

On September 30, 2010, Léo Apotheker was named HP's new CEO and president. His appointment sparked a strong reaction from Ellison, who complained that Apotheker had been in charge of SAP when one of its subsidiaries was systematically stealing software from Oracle. SAP accepted that its subsidiary, which has now closed, illegally accessed Oracle intellectual property. Following Hurd's departure, HP was seen to be problematic by the market, with margins falling and having failed to redirect and establish itself in major new markets such as cloud and mobile services. Apotheker's strategy was to broadly aim at disposing hardware and moving into the more profitable software services sector. On August 18, 2011, HP announced that it would strategically exit the smartphone and tablet computer business, and focus on higher-margin "strategic priorities of Cloud, solutions and software with an emphasis on enterprise, commercial and government markets". It also contemplated selling off its personal computer division or spinning it off into a separate company, and quitting PC development while continuing to sell servers and other equipment to business customers, which was a strategy undertaken by IBM in 2005.

HP's stock dropped by about a further 40% after the company abruptly announced a number of decisions: to discontinue its webOS device business (mobile phones and tablet computers), the intent to sell its personal computer division (at the time HP was the largest personal computer manufacturer in the world), and to acquire British big data software firm Autonomy for a 79% premium, seen externally as an "absurdly high" price for a business with known concerns over its accounts. Media analysts described HP's actions as a "botched strategy shift" and a "chaotic" attempt to rapidly reposition HP and enhance earnings. The Autonomy acquisition was objected to by HP's own CFO.

HP lost more than $30 billion in market capitalization during Apotheker's tenure, and on September 22, 2011, the HP Board of Directors fired him as chief executive and replaced him with fellow board member and former eBay chief Meg Whitman, with Raymond J. Lane as executive chairman. Although Apotheker served barely ten months, he received over $13 million in compensation. Weeks later, HP announced that a review had concluded their PC division was too integrated and critical to business operations, and the company reaffirmed their commitment to the Personal Systems Group. In November 2012, HP wrote off almost $9 billion related to the Autonomy acquisition, which became the subject of intense litigation, as HP accused Autonomy's previous management of fraudulently exaggerating Autonomy's financial position and called in law enforcement and regulators in both countries, while Autonomy's previous management accused HP of "textbook" obfuscation and finger pointing to protect HP's executives from criticism and conceal HP culpability, their prior knowledge of Autonomy's financial position, and gross mismanagement of Autonomy after acquisition.

On March 21, 2012, HP said its printing and PC divisions would become one unit headed by Todd Bradley from the PC division, and printing chief Vyomesh Joshi left the company.

On May 23, 2012, HP announced plans to lay off approximately 27,000 employees, after posting a profit decline of 31% in the second quarter of 2012. Profits declined because of the growing popularity of smart phones, tablets, and other mobile devices, which slowed down personal computer sales.

On May 30, 2012, HP unveiled its first net zero energy data center, which used solar energy and other renewable sources instead of traditional power grids.

On July 10, 2012, HP's Server Monitoring Software was discovered to have a previously unknown security vulnerability. A security warning was given to customers about two vulnerabilities, and a patch addressing the issues was released. One month later, HP's official training center was hacked and defaced by a Pakistani hacker known as Hitcher to demonstrate a Web vulnerability.

On September 10, 2012, HP revised their restructuring figures and started cutting 29,000 jobs.

2013–2015

On December 31, 2013, HP revised the number of jobs cut from 29,000 to 34,000 up to October 2014. The number of jobs cut until the end of 2013 was 24,600. At the end of 2013 the company had 317,500 employees. On May 22, 2014, HP announced it would cut a further 11,000 to 16,000 jobs, in addition to the 34,000 announced in 2013. Whitman said: "We are gradually shaping HP into a more nimble, lower-cost, more customer and partner-centric company that can successfully compete across a rapidly changing IT landscape."

During the June 2014 HP Discover customer event in Las Vegas, Whitman and Martin Fink announced a project for a radically new computer architecture called The Machine. Based on memristors and silicon photonics, it was supposed to come into commercialization before the end of the decade, and represented 75% of the research activity in HP Labs at the time.

On October 6, 2014, HP announced it was going to split into two separate companies to separate its personal computer and printer businesses from its technology services. The split, which was first reported by The Wall Street Journal and confirmed by other media, resulted in two publicly traded companies on November 1, 2015: Hewlett Packard Enterprise and HP Inc. The split was structured so that Hewlett-Packard changed its name to HP Inc. and spun off Hewlett Packard Enterprise as a new publicly traded company. Whitman became chairman of HP Inc. and CEO of Hewlett Packard Enterprise, Patricia Russo became chairman of the enterprise business, and Dion Weisler became CEO of HP, Inc.

On October 29, 2014, Hewlett-Packard announced their new Sprout personal computer.

In May 2015, the company announced it would be selling its controlling 51 percent stake in its Chinese data-networking business to Tsinghua Unigroup for a fee of at least $2.4 billion.

Facilities

HP's global operations were directed from its headquarters in Palo Alto, California. Its US operations were directed from its facility in an unincorporated area of Harris County, Texas, near Houston. Its Latin America offices were in unincorporated Miami-Dade County, Florida. Its European offices were in Meyrin, close to Geneva, Switzerland, but it also had a research center in the Paris-Saclay cluster 20 km south of Paris, France. Its Asia-Pacific offices were in Singapore.

It also had large operations in Leixlip, Ireland; Austin, Texas; Boise, Idaho; Corvallis, Oregon; Fort Collins, Colorado; Roseville, California; Saint Petersburg, Florida; San Diego, California; Tulsa, Oklahoma; Vancouver, Washington; Conway, Arkansas; and Plano, Texas. In the UK, HP was based at a large site in Bracknell, Berkshire, with offices in various UK locations, including a landmark office tower in London, 88 Wood Street. Its acquisition of 3Com expanded its employee base to Marlborough, Massachusetts, where it has been manufacturing its convertible laptop series since late 2019. The company also had a large workforce and numerous offices in Bucharest, Romania, and at Bangalore, India, to address their back end and IT operations. Mphasis, which is headquartered at Bangalore, also enabled HP to increase their footprint in the city as it was a subsidiary of EDS which the company acquired.

Products and organizational structure

HP produced lines of printers, scanners, digital cameras, calculators, personal digital assistants, servers, workstation computers, and computers for home and small-business use; many of the computers came from the 2002 merger with Compaq. HP as of 2001 promoted itself as supplying not just hardware and software, but also a full range of services to design, implement, and support IT infrastructure.

HP's Imaging and Printing Group (IPG) was described by the company in 2005 as "the leading imaging and printing systems provider in the world for printer hardware, printing supplies and scanning devices, providing solutions across customer segments from individual consumers to small and medium businesses to large enterprises".

Products and technology associated with IPG included the Inkjet and LaserJet printers, the Officejet all-in-one multifunction printer/scanner/faxes, Indigo Digital Press, the HP Photosmart digital cameras and photo printers, and the photo sharing service Snapfish.

HP's Personal Systems Group (PSG) was claimed by HP in 2005 to be "one of the leading vendors of personal computers ("PCs") in the world based on unit volume shipped and annual revenue". PSG dealt with business and consumer PCs and accessories (such as e.g., HP Pavilion, Compaq Presario, and VoodooPC), handheld computing (e.g., iPAQ Pocket PC), digital "connected" entertainment (e.g., HP MediaSmart TVs, HP MediaSmart Servers, HP MediaVaults, DVD+RW drives) and Apple's iPod (until November 2005).

HP Enterprise Business (EB) incorporated HP Technology Services and Enterprise Services (an amalgamation of the former EDS, and what was known as HP Services). HP Enterprise Security Services oversaw professional services such as network security, information security and information assurance/compliancy, HP Software Division, and Enterprise Servers, Storage and Networking Group (ESSN). The Enterprise Servers, Storage and Networking Group (ESSN) oversaw "back end" products like storage and servers. HP Networking (former ProCurve) was responsible for the NW family of products.

From September 2005 HP purchased several software companies as part of a publicized, deliberate strategy to augment its software offerings for large business customers. HP Software sold several categories of software, which included business service management software, application lifecycle management software, mobile apps, and enterprise security software (the latter of which included, ArcSight, Fortify Software, Atalla and TippingPoint). HP Software also provided software as a service (SaaS), cloud computing solutions, and software services, including consulting, education, professional services, and support.

HP's Office of Strategy and Technology had four main functions: To steer the company's $3.6 billion research and development investment; foster the development of the company's global technical community; lead the company's strategy and corporate development efforts, and perform worldwide corporate marketing activities.

HP Labs served as the research arm of HP.

HP also offered managed services by which they provide complete IT-support solutions for other companies and organizations. One example of these was offering "Professional Support" and desktop "Premier Support" for Microsoft in the EMEA marketplace. This was done from the Leixlip campus near Dublin, Sofia and Israel. Support was offered for Microsoft Windows, Exchange, SharePoint, and some office applications.

Corporate social responsibility

In July 2007, the company announced that it had met its 2004 target to recycle one billion pounds of electronics, toner, and ink cartridges. It set a new goal of recycling a further two billion pounds of hardware by the end of 2010. In 2006, the company recovered 187 million pounds of electronics.

In 2008, HP released its supply chain emissions data.

In September 2009, Newsweek ranked HP No. 1 on its 2009 Green Rankings of America's 500 largest corporations. According to Environmental Leader (now Environment + Energy Leader), "Hewlett-Packard earned its number one position due to its greenhouse gas (GHG) emission reduction programs, and was the first major IT company to report GHG emissions associated with its supply chain, according to the ranking. In addition, HP has made an effort to remove toxic substances from its products, though Greenpeace has targeted the company for not doing better."

HP took the top spot on Corporate Responsibility Magazine's 100 Best Corporate Citizens List for 2010. HP beat out other Russell 1000 Index companies because of its leadership in seven categories including environment, climate changes and corporate philanthropy. In 2009, HP was ranked fifth.

Fortune magazine named HP one of the World's Most Admired Companies in 2010, placing it No. 2 in the computer industry and No. 32 overall in its list of the top 50. This year in the computer industry HP was ranked No. 1 in social responsibility, long-term investment, global competitiveness, and use of corporate assets.

In May 2011, HP released a Global Responsibility report covering accomplishments in 2010. It provides a comprehensive view of HP's global citizenship programs, performance, and goals and describes how HP used its technology, influence, and expertise to make a positive impact on the world. The company's 2009 report won best corporate responsibility report of the year, and claims HP decreased its total energy use by 9 percent when compared with 2008. HP recovered a total of 118,000 tonnes of electronic products and supplies for recycling in 2009, including 61 million print cartridges.

In an April 2010 San Francisco Chronicle article, HP was one of 12 companies commended for "designing products to be safe from the start, following the principles of green chemistry". The commendations came from Environment California, an environmental advocacy group, who praised select companies in the Golden State and the Bay Area for their conservational efforts.

In May 2010, HP was named one of the World's Most Ethical Companies by Ethisphere Institute. It was one of 100 companies to earn the distinction of top winner and was the only computer hardware vendor to be recognized.

HP was listed in Greenpeace's Guide to Greener Electronics that ranks electronics manufacturers according to their policies on sustainability, energy and climate, and green products. In November 2011, HP secured first place (out of 15) in this ranking with a score of 5.9. It scored the most points on the new Sustainable Operations criteria, having the best program for measuring and reducing emissions of greenhouse gases from its suppliers and scoring maximum points for its thorough paper procurement policy. In the November 2012 report, HP was ranked second with a score of 5.7.

HP earned recognition of its work in data privacy and security. In 2010 the company ranked No. 4 in the Ponemon Institute's annual study of the most trusted companies for privacy. Since 2006, HP has worked directly with the U.S. Congress, the Federal Trade Commission (FTC), and the Department of Commerce to establish a new strategy for federal legislation. HP played a key role in work toward the December 2010 FTC report "Protecting Consumer Privacy in an Era of Rapid Change".

After winning nine straight annual "Most Respected Company in China" awards from the Economic Observer and Peking University, HP China added the "10 Year Contribution" award to its list of accolades.

In its 2012 rankings of consumer electronics companies on progress relating to conflict minerals, the Enough Project rated HP second out of 24 companies.

Brand

The company sponsored the HP Pavilion at San Jose (now SAP Center at San Jose), home to the NHL's San Jose Sharks.

According to a 2009 BusinessWeek study, HP was the world's 11th most valuable brand.

HP had many sponsorships, such as Mission: SPACE in Epcot at the Walt Disney World Resort. From 1995 to 1999, and again from 2013, HP had been the shirt sponsor of Premier League club Tottenham Hotspur F.C. From 1997 to 1999 they sponsored Australian Football League club North Melbourne Football Club. They also sponsored the Jordan Grand Prix from 1999 to 2001, Stewart Grand Prix in 1999, Jaguar Racing from 2000 to 2002, BMW Williams Formula 1 team until 2005 (a sponsorship formerly held by Compaq), and since 2010 sponsored Renault F1. HP also had the naming rights arrangement for the HP Pavilion at San Jose, whose naming rights were acquired by SAP AG and consequently renamed SAP Center at San Jose. HP also maintained a number of corporate sponsorships in the business sector, including sponsorships of trade organisations including Fespa (print trade exhibitions), and O'Reilly Media's Velocity (web development) conference.

After the acquisition of Compaq in 2002, HP maintained the Compaq Presario brand on low-end home desktops and laptops, the HP Compaq brand on business desktops and laptops, and the HP ProLiant brand on Intel-architecture servers. The HP Pavilion brand was used on home entertainment laptops and all home desktops.

Tandem's "NonStop" servers were rebranded as "HP Integrity NonStop".

Controversies

Restatement

In March 2003, HP restated its first-quarter cash flow from operations, reducing it by 18 percent because of an accounting error. The actual cash flow from operations was $647 million, and not $791 million as reported; HP shifted $144 million to net cash used in investing activities.

Spying scandal

On September 5, 2006, Shawn Cabalfin and David O'Neil of Newsweek wrote that HP's general counsel, at the behest of chairwoman Patricia Dunn, contracted a team of independent security experts to investigate board members and several journalists to identify the source of an information leak. In turn, those security experts recruited private investigators who used pretexting, which involved investigators impersonating HP board members and nine journalists (including reporters for CNET, The New York Times and The Wall Street Journal) in order to obtain their phone records. The information leaked related to HP's long-term strategy and was published as part of a CNET article in January 2006. Most HP employees accused of criminal acts have since been acquitted.

Hardware

In November 2007, HP released a BIOS update covering a wide range of laptops with the intent to speed up the computer fan and have it run constantly while the computer was on or off to prevent the overheating of defective Nvidia graphics processing units (GPUs) that had been shipped to many of the original equipment manufacturers, including HP, Dell, and Apple. The defect concerned the new packaging material used by Nvidia from 2007 onwards in joining the graphics chip onto the motherboard, which did not perform well under thermal cycling and was prone to develop stress cracks – effectively severing the connection between the GPU and the motherboard that led to a blank screen. In July 2008, HP issued an extension to the initial one-year warranty to replace the motherboards of selected models. However this option was not extended to all models with the defective Nvidia chipsets, despite research showing that these computers were also affected by the fault. Furthermore, the replacement of the motherboard was a temporary fix, since the fault was inherent in all units of the affected models from the point of manufacture, including the replacement motherboards offered by HP as a free "repair". Since then, several websites have been documenting the issue. There have been several small-claims lawsuits filed in several states, as well as suits filed in other countries. HP also faced a class-action lawsuit in 2009 over its i7 processor computers: the complainants stated that their systems consistently locked up within 30 minutes of powering on. Even after being replaced with newer i7 systems, the lockups continued.

Lawsuit against Oracle

HP filed a lawsuit in California Superior Court in Santa Clara, claiming that Oracle had breached an agreement to support the Itanium microprocessor used in HP's high-end enterprise servers. On June 15, 2011, HP sent a "formal legal demand" letter to Oracle in an attempt to force them to reverse its decision to discontinue software development on Intel Itanium microprocessors and build its own servers. HP won the lawsuit in 2012, which required Oracle to continue producing software compatible with the Itanium processor. HP was awarded $3 billion in damages against Oracle on June 30, 2016, arguing that Oracle canceling support damaged HP's Itanium server brand. Oracle said it would appeal both the decision and damages.

HP wage and hour lawsuit

Several class action firms filed a class action lawsuit on January 12, 2012, against HP Inc. and Hewlett Packard Enterprise (“HP”), entitled "Jeffrey Wall, etc. v. HP, Inc." (formerly known as Hewlett-Packard Company, et al.), Case No. 30-2012-00537897, pending in the Superior Court of California, County of Orange. According to the lawsuit, HP allegedly failed to pay commission payments and incentive compensation that its California sales employees were owed within the timeframes proscribed by California law (Labor Code §§ 201, 202 and 204). In 2017, FDAzar obtained a settlement of $25 million for class participants and changed the way HP pays incentive compensation and commission payments.

Takeover of Autonomy

In November 2012, HP recorded a write-down of around $8.8 billion related to its acquisition a year earlier of the UK-based Autonomy Corporation PLC. HP accused Autonomy of deliberately inflating the value of the company prior to its takeover, which the former management team of Autonomy denied.

At the time, HP had fired its previous CEO for expenses irregularities a year before, and appointed Apotheker as CEO and president. HP was seen as problematic by the market, with margins falling and having failed to redirect and establish itself in major new markets such as cloud and mobile services.

As part of Apotheker's strategy, Autonomy was acquired by HP in October 2011. HP paid $10.3 billion for 87.3% of the shares, valuing Autonomy at around $11.7 billion (£7.4 billion) overall, a premium of around 79% over market price. The deal was widely criticized as "absurdly high", a "botched strategy shift" and a "chaotic" attempt to rapidly reposition HP and enhance earnings, and had been objected to even by HP's own CFO. Within a year, Apotheker was fired, major culture clashes became apparent, and HP wrote off $8.8 billion of Autonomy's value.

HP claimed that this resulted from "accounting improprieties, misrepresentations and disclosure failures" by the previous management, who in turn accused HP of a "textbook example of defensive stalling" to conceal evidence of its own prior knowledge, gross mismanagement, and undermining of the company, noting public awareness since 2009 of its financial reporting issues and that even HP's CFO disagreed with the price paid. External observers generally stated that only a small part of the write-off appears to be due to accounting mis-statements, and that HP had previously overpaid for businesses.

The Serious Fraud Office (SFO) and the SEC joined the FBI in investigating the potential anomalies. HP incurred damage with its stock falling to its lowest in decades. Three lawsuits were brought by shareholders against HP for the fall in value of HP shares. In August 2014, a United States district court judge threw out a proposed settlement, which Autonomy's previous management had argued would be collusive and intended to divert scrutiny of HP's own responsibility and knowledge. It essentially engaged the plaintiff's attorneys from the existing cases and redirected them against the previous Autonomy vendors and management for a fee of up to $48 million, with plaintiffs agreeing to end any claims against HP's management and similarly redirect those claims against the previous Autonomy vendors and management. In January 2015 the SFO closed its investigation as the likelihood of a successful prosecution was low. The dispute continued in the US, and is being investigated by the UK and Ireland Financial Reporting Council. On June 9, 2015, HP agreed to pay $100 million to investors who bought HP shares between August 19, 2011, and November 20, 2012, to settle the lawsuits over the Autonomy purchase.

Another term of the shareholder settlement was to sue Autonomy management, which occurred in London in 2019. HP "failed to produce a smoking gun for the fraud it alleges", and its accountants admitted that they "never formally prepared anything to attribute the irregularities to the amount of the fraud".

Israeli settlements

On October 25, 2012, Richard Falk, the United Nations Human Rights Council's Special Rapporteur on the situation of human rights in the Palestinian territories occupied since 1967, called to boycott HP and other businesses that profit from Israeli settlements on occupied Palestinian lands until they brought their operations in line with international human rights and humanitarian law. In 2014, the Presbyterian Church voted to move forward with divestment from HP to pressure Israeli in regards to their policies toward Palestinians. In 2015, the Human Rights Commission of Portland, Oregon, requested to place Caterpillar, G4S, HP, and Motorola Solutions on the city's "Do Not Buy" list.

Bribery

On April 9, 2014, an administrative proceeding before the SEC was settled by HP consenting to an order acknowledging that HP had violated the Foreign Corrupt Practices Act (FCPA) when HP subsidiaries in Russia, Poland, and Mexico made improper payments to government officials to obtain or retain lucrative public contracts.

The SEC's order found that HP's subsidiary in Russia paid more than $2 million through agents and various shell companies to a Russian government official to retain a multimillion-dollar contract with the federal prosecutor's office; in Poland, HP's subsidiary provided gifts and cash bribes worth more than $600,000 to a Polish government official to obtain contracts with the national police agency; and to win a software sale to Mexico's state-owned petroleum company, HP's subsidiary in Mexico paid more than $1 million in inflated commissions to a consultant with close ties to company officials, one of whom was funneled money. HP agreed to pay $108 million to settle the SEC charges and a parallel criminal case.

Dynamic security cartridge blocking

"Dynamic security" was part of HP’s cartridge authentication process that was first introduced in 2016, resulting in printing in some printers being disabled via firmware updates if they use ink or toner cartridges which did not contain “new or reused HP chips or electronic circuitry.” As a result, HP faced scathing criticism (such as that from the Electronic Frontier Foundation) and paid millions in class-action lawsuits, such as to certain customers in the US, Australia, and Italy, but without admitting wrongdoing. HP's position was that dynamic security was about bringing "the best consumer experience" and protecting customers "from counterfeit and third-party ink cartridges that do not contain an original HP security chip and that infringe on our IP."

The issue resurfaced again in early 2023, when some users re-discovered that HP Inc. prevents unauthorized cartridges from being used. HP Inc. offers a firmware update for a few printers that will enable them to use third-party ink. Some ink resellers advise turning off the Dynamic Security feature on HP printers in order to use aftermarket cartridges.

Loss of company archives under Keysight

a large part of Hewlett-Packard's historical company archives (consisting of over 100 boxes of correspondence and documents from the two founders) were acquired by Keysight Technologies at the time of its foundation in 2014. These archives were completely lost when the 2017 Tubbs wildfire incinerated two buildings on the headquarters campus of Keysight in Santa Rosa, California. A former HP employee who had previously been in charge of the archives commented that "a huge piece of American business history is gone", and Keysight disputed criticism that the archives had been inadequately protected

 

Software engineering

From Wikipedia, the free encyclopedia

Software engineering is an engineering-based approach to software development. A software engineer is a person who applies the engineering design process to design, develop, maintain, test, and evaluate computer software. The term programmer is sometimes used as a synonym, but may also refer more to implementation rather than design and can also lack connotations of engineering education or skills.

Engineering techniques are used to inform the software development process, which involves the definition, implementation, assessment, measurement, management, change, and improvement of the software life cycle process itself. It heavily uses software configuration management, which is about systematically controlling changes to the configuration, and maintaining the integrity and traceability of the configuration and code throughout the system life cycle. Modern processes use software versioning.

History

Beginning in the 1960s, software engineering was seen as its own type of engineering. Additionally, the development of software engineering was seen as a struggle. It was difficult to keep up with the hardware which caused many problems for software engineers. Problems included software that was over budget, exceeded deadlines, required extensive de-bugging and maintenance, and unsuccessfully met the needs of consumers or was never even completed. In 1968 NATO held the first Software Engineering conference where issues related to software were addressed: guidelines and best practices for the development of software were established.

The origins of the term "software engineering" have been attributed to various sources. The term "software engineering" appeared in a list of services offered by companies in the June 1965 issue of COMPUTERS and AUTOMATION and was used more formally in the August 1966 issue of Communications of the ACM (Volume 9, number 8) "letter to the ACM membership" by the ACM President Anthony A. Oettinger, it is also associated with the title of a NATO conference in 1968 by Professor Friedrich L. Bauer, the first conference on software engineering. Margaret Hamilton described the discipline "software engineering" during the Apollo missions to give what they were doing legitimacy. At the time there was perceived to be a "software crisis". The 40th International Conference on Software Engineering (ICSE 2018) celebrates 50 years of "Software Engineering" with the Plenary Sessions' keynotes of Frederick Brooks and Margaret Hamilton.

In 1984, the Software Engineering Institute (SEI) was established as a federally funded research and development center headquartered on the campus of Carnegie Mellon University in Pittsburgh, Pennsylvania, United States. Watts Humphrey founded the SEI Software Process Program, aimed at understanding and managing the software engineering process. The Process Maturity Levels introduced would become the Capability Maturity Model Integration for Development(CMMI-DEV), which has defined how the US Government evaluates the abilities of a software development team.

Modern, generally accepted best-practices for software engineering have been collected by the ISO/IEC JTC 1/SC 7 subcommittee and published as the Software Engineering Body of Knowledge (SWEBOK). Software engineering is considered one of major computing disciplines.

Definitions and terminology

Notable definitions of software engineering include:

  • "The systematic application of scientific and technological knowledge, methods, and experience to the design, implementation, testing, and documentation of software"—The Bureau of Labor Statistics—IEEE Systems and software engineering – Vocabulary
  • "The application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software"—IEEE Standard Glossary of Software Engineering Terminology
  • "an engineering discipline that is concerned with all aspects of software production"—Ian Sommerville
  • "the establishment and use of sound engineering principles in order to economically obtain software that is reliable and works efficiently on real machines"—Fritz Bauer
  • "a branch of computer science that deals with the design, implementation, and maintenance of complex computer programs"—Merriam-Webster
  • "'software engineering' encompasses not just the act of writing code, but all of the tools and processes an organization uses to build and maintain that code over time. [...] Software engineering can be thought of as 'programming integrated over time.'"—Software Engineering at Google

The term has also been used less formally:

  • as the informal contemporary term for the broad range of activities that were formerly called computer programming and systems analysis;
  • as the broad term for all aspects of the practice of computer programming, as opposed to the theory of computer programming, which is formally studied as a sub-discipline of computer science;
  • as the term embodying the advocacy of a specific approach to computer programming, one that urges that it be treated as an engineering discipline rather than an art or a craft, and advocates the codification of recommended practices.

Etymology of "software engineer"

Margaret Hamilton promoted the term "software engineering" during her work on the Apollo program. The term "engineering" was used to acknowledge that the work should be taken just as seriously as other contributions toward the advancement of technology. Hamilton details her use of the term:

When I first came up with the term, no one had heard of it before, at least in our world. It was an ongoing joke for a long time. They liked to kid me about my radical ideas. It was a memorable day when one of the most respected hardware gurus explained to everyone in a meeting that he agreed with me that the process of building software should also be considered an engineering discipline, just like with hardware. Not because of his acceptance of the new "term" per se, but because we had earned his and the acceptance of the others in the room as being in an engineering field in its own right.

Suitability of the term

Individual commentators have disagreed sharply on how to define software engineering or its legitimacy as an engineering discipline. David Parnas has said that software engineering is, in fact, a form of engineering. Steve McConnell has said that it is not, but that it should be. Donald Knuth has said that programming is an art and a science. Edsger W. Dijkstra claimed that the terms software engineering and software engineer have been misused and should be considered harmful, particularly in the United States.

Tasks in large scale projects

Software requirements

Requirements engineering is about the elicitation, analysis, specification, and validation of requirements for software. Software requirements can be of three different types. There are functional requirements, non-functional requirements, and domain requirements. The operation of the software should be performed and the proper output should be expected for the user to use. Non-functional requirements deal with issues like portability, security, maintainability, reliability, scalability, performance, reusability, and flexibility. They are classified into the following types: interface constraints, performance constraints (such as response time, security, storage space, etc.), operating constraints, life cycle constraints (maintainability, portability, etc.), and economic constraints. Knowledge of how the system or software works is needed when it comes to specifying non-functional requirements. Domain requirements have to do with the characteristic of a certain category or domain of projects.

Software design

Software design is about the process of defining the architecture, components, interfaces, and other characteristics of a system or component. This is also called software architecture. Software design is divided into three different levels of design. The three levels are interface design, architectural design, and detailed design. Interface design is the interaction between a system and its environment. This happens at a high level of abstraction along with the inner workings of the system. Architectural design has to do with the major components of a system and their responsibilities, properties, interfaces, and their relationships and interactions that occur between them. Detailed design is the internal elements of all the major system components, their properties, relationships, processing, and usually their algorithms and the data structures.

Software construction

Software construction, the main activity of software development, is the combination of programming, unit testing, integration testing, and debugging so as to implement the design. Testing during this phase is generally performed by the programmer while the software is under construction, to verify what was just written and decide when the code is ready to be sent to the next step.

Software testing

Software testing is an empirical, technical investigation conducted to provide stakeholders with information about the quality of the product or service under test, with different approaches such as unit testing and integration testing. It is one aspect of software quality. As a separate phase in software development, it is typically performed by quality assurance staff or a developer other than the one who wrote the code.

Software analysis

Software analysis is the process of analyzing the behavior of computer programs regarding a property such as performance, robustness, and security It can be performed without executing the program (static program analysis), during runtime (dynamic program analysis) or in a combination of both.

Software maintenance

Software maintenance refers to the activities required to provide cost-effective support after shipping the software product. Software maintenance is modifying and updating software applications after distribution to correct faults and to improve its performance. Software has a lot to do with the real world and when the real world changes, software maintenance is required. Software maintenance includes: error correction, optimization, deletion of unused and discarded features, and enhancement of features that already exist. Usually, maintenance takes up about 40% to 80% of the project cost therefore, focusing on maintenance keeps the costs down.

Education

Knowledge of computer programming is a prerequisite for becoming a software engineer. In 2004 the IEEE Computer Society produced the SWEBOK, which has been published as ISO/IEC Technical Report 1979:2005, describing the body of knowledge that they recommend to be mastered by a graduate software engineer with four years of experience. Many software engineers enter the profession by obtaining a university degree or training at a vocational school. One standard international curriculum for undergraduate software engineering degrees was defined by the Joint Task Force on Computing Curricula of the IEEE Computer Society and the Association for Computing Machinery, and updated in 2014. A number of universities have Software Engineering degree programs; as of 2010, there were 244 Campus Bachelor of Software Engineering programs, 70 Online programs, 230 Masters-level programs, 41 Doctorate-level programs, and 69 Certificate-level programs in the United States.

In addition to university education, many companies sponsor internships for students wishing to pursue careers in information technology. These internships can introduce the student to interesting real-world tasks that typical software engineers encounter every day. Similar experience can be gained through military service in software engineering.

Software engineering degree programs

Half of all practitioners today have degrees in computer science, information systems, or information technology. A small, but growing, number of practitioners have software engineering degrees. In 1987, the Department of Computing at Imperial College London introduced the first three-year software engineering Bachelor's degree in the UK and the world; in the following year, the University of Sheffield established a similar program. In 1996, the Rochester Institute of Technology established the first software engineering bachelor's degree program in the United States, however, it did not obtain ABET accreditation until 2003, the same time as Rice University, Clarkson University, Milwaukee School of Engineering and Mississippi State University obtained theirs. In 1997, PSG College of Technology in Coimbatore, India was the first to start a five-year integrated Master of Science degree in Software Engineering.

Since then, software engineering undergraduate degrees have been established at many universities. A standard international curriculum for undergraduate software engineering degrees, SE2004, was defined by a steering committee between 2001 and 2004 with funding from the Association for Computing Machinery and the IEEE Computer Society. As of 2004, in the U.S., about 50 universities offer software engineering degrees, which teach both computer science and engineering principles and practices. The first software engineering Master's degree was established at Seattle University in 1979. Since then graduate software engineering degrees have been made available from many more universities. Likewise in Canada, the Canadian Engineering Accreditation Board (CEAB) of the Canadian Council of Professional Engineers has recognized several software engineering programs.

In 1998, the US Naval Postgraduate School (NPS) established the first doctorate program in Software Engineering in the world. Additionally, many online advanced degrees in Software Engineering have appeared such as the Master of Science in Software Engineering (MSE) degree offered through the Computer Science and Engineering Department at California State University, Fullerton. Steve McConnell opines that because most universities teach computer science rather than software engineering, there is a shortage of true software engineers. ETS (École de technologie supérieure) University and UQAM (Université du Québec à Montréal) were mandated by IEEE to develop the Software Engineering Body of Knowledge (SWEBOK), which has become an ISO standard describing the body of knowledge covered by a software engineer.

Profession

Legal requirements for the licensing or certification of professional software engineers vary around the world. In the UK, there is no licensing or legal requirement to assume or use the job title Software Engineer. In some areas of Canada, such as Alberta, British Columbia, Ontario, and Quebec, software engineers can hold the Professional Engineer (P.Eng) designation and/or the Information Systems Professional (I.S.P.) designation. In Europe, Software Engineers can obtain the European Engineer (EUR ING) professional title.

In the United States, the NCEES began offering a Professional Engineer exam for Software Engineering in 2013, thereby allowing Software Engineers to be licensed and recognized. NCEES ended the exam after April 2019 due to lack of participation. Mandatory licensing is currently still largely debated, and perceived as controversial.

The IEEE Computer Society and the ACM, the two main US-based professional organizations of software engineering, publish guides to the profession of software engineering. The IEEE's Guide to the Software Engineering Body of Knowledge – 2004 Version, or SWEBOK, defines the field and describes the knowledge the IEEE expects a practicing software engineer to have. The most current SWEBOK v3 is an updated version and was released in 2014. The IEEE also promulgates a "Software Engineering Code of Ethics".

Employment

There are an estimated 26.9 million professional software engineers in the world as of 2022, up from 21 million in 2016.

Many software engineers work as employees or contractors. Software engineers work with businesses, government agencies (civilian or military), and non-profit organizations. Some software engineers work for themselves as freelancers. Some organizations have specialists to perform each of the tasks in the software development process. Other organizations require software engineers to do many or all of them. In large projects, people may specialize in only one role. In small projects, people may fill several or all roles at the same time. Many companies hire interns, often university or college students during a summer break, or externships. Specializations include analysts, architects, developers, testers, technical support, middleware analysts, project managers, educators, and researchers.

Most software engineers and programmers work 40 hours a week, but about 15 percent of software engineers and 11 percent of programmers worked more than 50 hours a week in 2008. Potential injuries in these occupations are possible because like other workers who spend long periods sitting in front of a computer terminal typing at a keyboard, engineers and programmers are susceptible to eyestrain, back discomfort, and hand and wrist problems such as carpal tunnel syndrome.

United States

The U. S. Bureau of Labor Statistics (BLS) counted 1,365,500 software developers holding jobs in the U.S. in 2018. Due to its relative newness as a field of study, formal education in software engineering is often taught as part of a computer science curriculum, and many software engineers hold computer science degrees. The BLS estimates from 2014 to 2024 that computer software engineering would increase by 17% . This is down from the 2012 to 2022 BLS estimate of 22% for software engineering. And, is further down from their 30% 2010 to 2020 BLS estimate. Due to this trend, job growth may not be as fast as during the last decade, as jobs that would have gone to computer software engineers in the United States would instead be outsourced to computer software engineers in countries such as India and other foreign countries. In addition, the BLS Job Outlook for Computer Programmers, 2014–24 predicts an −8% (a decline, in their words), then a decline in the Job Outlook, 2019-29 of -9%, and a 10% decline for 2021-2031 for those who program computers. Furthermore, women in many software fields has also been declining over the years as compared to other engineering fields. Then there is the additional concern that recent advances in Artificial Intelligence might impact the demand for future generations of Software Engineers. However, this trend may change or slow in the future as many current software engineers in the U.S. market leave the profession or age out of the market in the next few decades.

Certification

The Software Engineering Institute offers certifications on specific topics like security, process improvement and software architecture. IBM, Microsoft and other companies also sponsor their own certification examinations. Many IT certification programs are oriented toward specific technologies, and managed by the vendors of these technologies. These certification programs are tailored to the institutions that would employ people who use these technologies.

Broader certification of general software engineering skills is available through various professional societies. As of 2006, the IEEE had certified over 575 software professionals as a Certified Software Development Professional (CSDP). In 2008 they added an entry-level certification known as the Certified Software Development Associate (CSDA). The ACM had a professional certification program in the early 1980s, which was discontinued due to lack of interest. The ACM examined the possibility of professional certification of software engineers in the late 1990s, but eventually decided that such certification was inappropriate for the professional industrial practice of software engineering.

In the U.K. the British Computer Society has developed a legally recognized professional certification called Chartered IT Professional (CITP), available to fully qualified members (MBCS). Software engineers may be eligible for membership of the Institution of Engineering and Technology and so qualify for Chartered Engineer status. In Canada the Canadian Information Processing Society has developed a legally recognized professional certification called Information Systems Professional (ISP). In Ontario, Canada, Software Engineers who graduate from a Canadian Engineering Accreditation Board (CEAB) accredited program, successfully complete PEO's (Professional Engineers Ontario) Professional Practice Examination (PPE) and have at least 48 months of acceptable engineering experience are eligible to be licensed through the Professional Engineers Ontario and can become Professional Engineers P.Eng. The PEO does not recognize any online or distance education however; and does not consider Computer Science programs to be equivalent to software engineering programs despite the tremendous overlap between the two. This has sparked controversy and a certification war. It has also held the number of P.Eng holders for the profession exceptionally low. The vast majority of working professionals in the field hold a degree in CS, not SE. Given the difficult certification path for holders of non-SE degrees, most never bother to pursue the license.

Impact of globalization

The initial impact of outsourcing, and the relatively lower cost of international human resources in developing third world countries led to a massive migration of software development activities from corporations in North America and Europe to India and later: China, Russia, and other developing countries. This approach had some flaws, mainly the distance / time zone difference that prevented human interaction between clients and developers and the massive job transfer. This had a negative impact on many aspects of the software engineering profession. For example, some students in the developed world avoid education related to software engineering because of the fear of offshore outsourcing (importing software products or services from other countries) and of being displaced by foreign visa workers. Although statistics do not currently show a threat to software engineering itself; a related career, computer programming does appear to have been affected. Nevertheless, the ability to smartly leverage offshore and near-shore resources via the follow-the-sun workflow has improved the overall operational capability of many organizations. When North Americans are leaving work, Asians are just arriving to work. When Asians are leaving work, Europeans are arriving to work. This provides a continuous ability to have human oversight on business-critical processes 24 hours per day, without paying overtime compensation or disrupting a key human resource, sleep patterns.

While global outsourcing has several advantages, global – and generally distributed – development can run into serious difficulties resulting from the distance between developers. This is due to the key elements of this type of distance that have been identified as geographical, temporal, cultural and communication (that includes the use of different languages and dialects of English in different locations). Research has been carried out in the area of global software development over the last 15 years and an extensive body of relevant work published that highlights the benefits and problems associated with the complex activity. As with other aspects of software engineering research is ongoing in this and related areas.

Prizes

There are several prizes in the field of software engineering:

  • The Codie awards is a yearly award issued by the Software and Information Industry Association for excellence in software development within the software industry.
  • Jolt Awards are awards in the software industry.
  • Stevens Award is a software engineering award given in memory of Wayne Stevens.
  • Harlan Mills Award for "contributions to the theory and practice of the information sciences, focused on software engineering".

Criticism

Software engineering sees its practitioners as individuals who follow well-defined engineering approaches to problem-solving. These approaches are specified in various software engineering books and research papers, always with the connotations of predictability, precision, mitigated risk and professionalism. This perspective has led to calls for licensing, certification and codified bodies of knowledge as mechanisms for spreading the engineering knowledge and maturing the field.

Software engineering extends engineering and draws on the engineering model, i.e. engineering process, engineering project management, engineering requirements, engineering design, engineering construction, and engineering validation. The concept is so new that it is rarely understood, and it is widely misinterpreted, including in software engineering textbooks, papers, and among the communities of programmers and crafters.

One of the core issues in software engineering is that its approaches are not empirical enough because a real-world validation of approaches is usually absent, or very limited and hence software engineering is often misinterpreted as feasible only in a "theoretical environment."

Edsger Dijkstra, the founder of many of the concepts used within software development today, rejected the idea of "software engineering" up until his death in 2002, arguing that those terms were poor analogies for what he called the "radical novelty" of computer science:

A number of these phenomena have been bundled under the name "Software Engineering". As economics is known as "The Miserable Science", software engineering should be known as "The Doomed Discipline", doomed because it cannot even approach its goal since its goal is self-contradictory. Software engineering, of course, presents itself as another worthy cause, but that is eyewash: if you carefully read its literature and analyse what its devotees actually do, you will discover that software engineering has accepted as its charter "How to program if you cannot."

The future of software engineering

New and emerging technologies combined with changing industry dynamics are set to bring about a transformative era in the realm of software engineering.

A recent report by Gartner shows that a significant shift towards low code and no code development is set to bring in more non-technical individuals into software development.

Additionally, the advent of artificial intelligence (AI) and machine learning (ML) will continue to play a crucial role in automating software development, all while improving the quality of software built.

The rise of cloud computing and DevOps will further accelerate software development processes and improve the pace of software delivery and deployment.

These modern technologies work with both structured and unstructured data and encourage the implementation of secure coding practices to ensure that the software built is reliable and secure
