Unlike the major six tool capabilities (see above), the following categories are introduced for the list, which correlate closer with the product marketing or summarizes capabilities, such as requirements management (including the elicitation, analysis and specification parts) and test management (meaning verification & validation capabilities).
Requirements engineering (RE) [1] is the process of defining, documenting, and maintaining requirements [2] in the engineering design process. It is a common role in systems engineering and software engineering .
Software requirements [1] 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: [2]
Requirements traceability is a sub-discipline of requirements management within software development and systems engineering.Traceability as a general term is defined by the IEEE Systems and Software Engineering Vocabulary [1] as (1) the degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor ...
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.
Requirements analysis strives to address these issues. There is an engineering trade off to consider between requirements which are too vague, and those which are so detailed that they take a long time to produce - sometimes to the point of being obsolete once completed; limit the implementation options available; are costly to produce
Formal Requirements Elicitation Tool (FRET) is a requirements engineering tool. It was developed by the NASA Ames Research Center to specify complex safety-critical systems whose failure could result in loss of life, significant property damage, or environmental harm. [3] FRET is open-source software released under the NASA Open Source ...
KAOS, is a goal-oriented software requirements capturing approach in requirements engineering. It is a specific Goal modeling method; another is i*. It allows for requirements to be calculated from goal diagrams. [1] KAOS stands for Knowledge Acquisition in automated specification [2] or Keep All Objectives Satisfied. [3]
