Requirement
In product development and process optimization, a requirement is a singular documented physical or functional need that a particular design, product or process aims to satisfy. It is commonly used in a formal sense in engineering design, including for example in systems engineering, software engineering, or enterprise engineering. It is a broad concept that could speak to any necessary (or sometimes desired) function, attribute, capability, characteristic, or quality of a system for it to have value and utility to a customer, organization, internal user, or other stakeholder. Requirements can come with different levels of specificity; for example, a requirement specification or requirement "spec" (often imprecisely referred to as "the" spec/specs, but there are actually different sorts of specifications) refers to an explicit, highly objective/clear (and often quantitative) requirement (or sometimes, ''set'' of requirements) to be satisfied by a material, design, product, or serv ...

Requirements Engineering
Requirements engineering (RE) is the process of defining, documenting, and maintaining requirements in the engineering design process. It is a common role in systems engineering and software engineering. The first use of the term ''requirements engineering'' was probably in 1964 in the conference paper "Maintenance, Maintainability, and System Requirements Engineering", but it did not come into general use until the late 1990s with the publication of an IEEE Computer Society tutorial in March 1997 and the establishment of a conference series on requirements engineering that has evolved into the International Requirements Engineering Conference. In the waterfall model, requirements engineering is presented as the first phase of the development process. Later development methods, including the Rational Unified Process (RUP) for software, assume that requirements engineering continues through a system's lifetime. Requirement management, which is a sub-function of Systems Enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goal Modeling
A goal model is an element of requirements engineering that may also be used more widely in business analysis. Related elements include stakeholder analysis, context analysis, and scenarios, among other business and technical areas. Principles Goals are objectives which a system should achieve through cooperation of actors in the intended software and in the environment. Goal modeling is especially useful in the early phases of a project. Projects may consider how the intended system meets organizational goals (see also ), why the system is needed and how the stakeholders’ interests may be addressed. A goal model: * Expresses the relationships between a system and its environment (i.e. not only on what the system is supposed to do, but why). The understanding this gives, of the reasons why a system is needed, in its context, is useful because "systems are increasingly used to fundamentally change business processes rather than to automate long-established practices". * Clarifies ...

Axel van Lamsweerde (born 1947) is a Belgian computer scientist and Professor of Computing Science at the Universite catholique de Louvain, known for his work on requirements engineering and the development of the KAOS goal-oriented modeling language. Biography Van Lamsweerde received his MS in Mathematics from the Université catholique de Louvain and his PhD in computing science from the Université libre de Bruxelles. Van Lamsweerde started his career as research associate at Philips Research Labs in 1970. In 1980 he was appointed Professor at the Université de Namur, and later also professor at the Université libre de Bruxelles, and research fellow at the University of Oregon and Stanford. From 1988 to 1990 he directed the ESPRIT ICARUS project. Late 1990s he was appointed Professor of Computing Science at the Universite catholique de Louvain, where he also directed the Software Engineering group in the "Departement d'Ingenierie Informatique".

Michigan State University
Michigan State University (Michigan State, MSU) is a public university, public Land-grant university, land-grant research university in East Lansing, Michigan. It was founded in 1855 as the Agricultural College of the State of Michigan, the first of its kind in the United States. It is considered a Public Ivy, or a public institution which offers an academic experience similar to that of an Ivy League university. After the introduction of the Morrill Land-Grant Acts, Morrill Act in 1862, the state designated the college a land-grant institution in 1863, making it the first of the land-grant colleges in the United States. The college became coeducational in 1870. In 1955, the state officially made the college a university, and the current name, Michigan State University, was adopted in 1964. Today, Michigan State has the largest undergraduate enrollment among Michigan's colleges and universities and approximately 634,300 living alums worldwide. The university is a member of the ...

Université Catholique De Louvain
The Université catholique de Louvain (also known as the Catholic University of Louvain, the English translation of its French name, and the University of Louvain, its official English name) is Belgium's largest French-speaking university. It is located in Louvain-la-Neuve, which was expressly built to house the university, and Brussels, Charleroi, Mons, Tournai and Namur. Since September 2018, the university has used the branding UCLouvain, replacing the acronym UCL, following a merger with Saint-Louis University, Brussels. The original University of Louvain (''Universitas Lovaniensis'') was founded at the centre of the historic town of Leuven (or ''Louvain'') in 1425, and abolished by the law in 1797 making it the first university in Belgium and the Low Countries. This university was the centre of Baianism, Jansenism and Febronianism in Europe. A new university, the State University of Louvain, was founded in 1817 and abolished by the law in 1835. A new catholic universit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Coimbra
The University of Coimbra (UC; pt, Universidade de Coimbra, ) is a Public university, public research university in Coimbra, Portugal. First established in Lisbon in 1290, it went through a number of relocations until moving permanently to Coimbra in 1537. The university is among the List of oldest universities in continuous operation, oldest universities in continuous operation in the world, the oldest in Portugal, and played an influential role in the development of higher education in the Lusophone, Portuguese-speaking world. In 2013, UNESCO declared the university a World Heritage Site, noting its architecture, unique culture and traditions, and historical role. The contemporary university is organized into eight faculty (division), faculties, granting bachelor's (''licenciado''), master's (''mestre'') and doctorate (''doutor'') degrees in nearly all major fields.

Stack Exchange
Stack Exchange is a network of question-and-answer (Q&A) websites on topics in diverse fields, each site covering a specific topic, where questions, answers, and users are subject to a reputation award process. The reputation system allows the sites to be self-moderating. As of August 2019, the three most actively-viewed sites in the network are Stack Overflow, Super User, and Ask Ubuntu. All sites in the network are modeled after the initial site Stack Overflow, a Q&A site for computer programming questions created by Jeff Atwood and Joel Spolsky. Further Q&A sites in the network are established, defined and eventually if found relevant brought to creation by registered users through a special site named Area 51.

Software Requirements
Software requirements for a system are the description of what the system should do, the service or services that it provides and the constraints on its operation. The IEEE Standard Glossary of Software Engineering Terminology defines a requirement as: # ''A condition or capability needed by a user to solve a problem or achieve an objective.'' # A condition or capability that must be met or possessed by a system or system component to satisfy a contract, standard, specification, or other formally imposed document. # A documented representation of a condition or capability as in 1 or 2. The activities related to working with software requirements can broadly be broken down into elicitation, analysis, specification, and management. Note that the wording ''Software requirements'' is additionally used in software release notes to explain, which depending software packages are required for a certain software to be built/installed/used. Elicitation Elicitation is the gathering and dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
