In software project management, software testing, and software engineering, verification and validation (V&V) is the process of checking that a software system meets specifications and that it fulfills its intended purpose.
 It may also be referred to as software quality control.
 It is normally the responsibility of software testers as part of the software development lifecycle.
 In simple terms, software verification is: "Assuming we should build X, does our software achieve its goals without any bugs or gaps?"
 On the other hand, software validation is: "Was X what we should have built?
 Does X meet the high level requirements?"
ENQUIRE was a software project written in 1980 by Tim Berners-Lee at CERN, which was the predecessor to the World Wide Web.
 It was a simple hypertext program that had some of the same ideas as the Web and the Semantic Web but was different in several important ways.
Albert Greenberg is an American software engineer and computer scientist who is notable for his contributions to the design of operating carrier and datacenter networks as well as to advances in computer networking and cloud computing.
 At Microsoft, he is a Distinguished Engineer and the director of development for its Microsoft Azure service, which is a cloud computing infrastructure platform which coordinates data centers around the world.
 In contrast to hard-wired computer networks, firms such as Microsoft are turning increasingly to software-defined networking (or SDN) approaches to run its cloud computing networks by managing virtual networks across "millions of servers".
 He oversees development of technologies that keep the network running in the cloud, so that when component failures happen, software systems pinpoint the failures and "route around the faulty components;" the technology permits data centers to be "software-defined", allowing the cloud to grow rapidly while being flexible to meet changing needs, as he explained in 2015 in "eWeek" magazine.
 His research focuses on the infrastructure of cloud services, management of enterprise networks, data center networks, and systems monitoring.
 Greenberg has won numerous awards for his contributions: he is an ACM Fellow, received the Koji Kobayashi Computers and Communications Award in 2015 for his "fundamental contributions to large-scale backbone networks and data-center networks," and won the prestigious SIGCOMM Award in 2015 for "pioneering the theory and practice of operating carrier and datacenter networks."
 In addition, he publishes in numerous scholarly journals on topics such as networking and cloud computing.
 He began his career at AT&T Labs and became division manager for network measurement engineering and research, was promoted to executive director and an AT&T Fellow, and was hired by Microsoft in 2007 as a principal researcher.
 In 2016, he was inducted into the United States National Academy of Engineering for "contributions to the theory and practice of operating large carrier and data center networks."
The Business Intelligence and Reporting Tools (BIRT) Project is an open source software project that provides reporting and business intelligence capabilities for rich client and web applications, especially those based on Java and Java EE.
 BIRT is a top-level software project within the Eclipse Foundation, an independent not-for-profit consortium of software industry vendors and an open source community.
Terry Benton Bollinger (born February 6, 1955, Fredericktown, Missouri) is an American computer scientist who works at the MITRE Corporation.
 In 2003 he wrote an influential report for the U.S. Department of Defense (U.S. DoD) in which he showed that free and open source software (FOSS) had already become a vital part of the United States Department of Defense software infrastructure, and that banning or restricting its use would have had serious detrimental impacts on DoD security, research capabilities, operational capabilities, and long-term cost efficiency.
 His report ended a debate about whether FOSS should be banned from U.S. DoD systems, and in time helped lead to the current official U.S. DoD policy of treating FOSS and proprietary software as equals.
 The report is referenced on the DoD CIO web site and has been influential in promoting broader recognition of the importance of free and open source software in government circles.
 Bollinger is also known for his activity in the IEEE Computer Society, where he was an editor for IEEE Software for six years, wrote the founding charter for "IEEE Security & Privacy Magazine", and received an "IEEE Third Millennium Medal" for lifetime contributions to "IEEE".
 He has written about a wide range of software issues including effective development processes, cyber security, and distributed intelligence.
Sir Timothy John Berners-Lee (born 8 June 1955), also known as TimBL, is an English engineer and computer scientist, best known as the inventor of the World Wide Web.
 He made a proposal for an information management system in March 1989, and he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the internet in mid-November the same year.
Trygve Mikkjel Heyerdahl Reenskaug (born 21 June 1930) is a Norwegian computer scientist and professor emeritus of the University of Oslo.
 He formulated the model–view–controller (MVC) pattern for graphical user interface (GUI) software design in 1979 while visiting the Xerox Palo Alto Research Center (PARC).
 His first major software project, "Autokon," produced a successful CAD/CAM program which was first used in 1963, and continued in use by shipyards worldwide for more than 30 years.
In the study of software project scheduling, the Putnam–Norden–Rayleigh curve, also known as the PNR curve, is an equation specifying the relationship between applied effort and delivery time for a software project.
 A PNR curve can be used to determine the least cost time for delivery formula_1 up to the limit formula_2, the absolute minimal amount of time required to complete the project no matter how many human resources are added.
 The PNR curve was used to derive the Software equation.
Brooks' law is an observation about software project management according to which "adding human resources to a late software project makes it later".
 It was coined by Fred Brooks in his 1975 book "The Mythical Man-Month".
 According to Brooks, there is an incremental person who, when added to a project, makes it take more, not less time.
 This is similar to the general law of diminishing returns in economics.
In the study of software project estimation, the Software Equation is a model with multiple variables based on assumptions of a specific distribution of effort throughout the entire length of a software development project.
 The models basis was formed through analysis of productivity data collected from over 4000 modern day software development projects.
 The software equation was derived from the Putnam-Norden-Rayleigh Curve which can be used to show the non-linear correlation between time to complete the project and applied human effort.
