Editing Software requirements specification (section)

== History ==
Software requirement specifications are already used in software development processes as early as 1975.<ref>{{Cite journal |last=Ramamoorthy |first=C. V. |last2=Ho |first2=S. F. |date=1975-04-01 |title=Testing large software with automated software evaluation systems |url=https://dl.acm.org/doi/10.1145/390016.808461 |journal=SIGPLAN Not. |volume=10 |issue=6 |pages=382–394 |doi=10.1145/390016.808461 |issn=0362-1340}}</ref> 

The purpose and content of software requirement specifications was formalised in 1983 by the [[Institute of Electrical and Electronics Engineers|IEEE]].  The standard was published in 1984 as IEEE-830-1984 and approved by [[American National Standards Institute|ANSI]].<ref>{{Cite web |title=IEEE Standards Association - IEE-830-1984 |url=https://standards.ieee.org/ieee/830/1220/ |access-date=2024-12-30 |website=IEEE Standards Association |language=en}}</ref> It was revised in 1993 and 1998, before being superseded by an international standard.<ref>{{Cite web |title=IEEE Standards Association - IEEE 839-1993 |url=https://standards.ieee.org/ieee/830/1221/ |access-date=2024-12-30 |website=IEEE Standards Association |language=en}}</ref><ref name=":0">{{Cite web |title=IEEE Standards Association IEEE 830-1998 |url=https://standards.ieee.org/ieee/830/1222/ |access-date=2024-12-30 |website=IEEE Standards Association |language=en}}</ref>  This standard aimed at providing criteria for a good SRS, and recommendations about its content. It recognised the benefits of prototyping for the requirement engineering.  It propose an example of structure and several variants.   

The [[International Organization for Standardization|ISO]]/IEC/IEEE 29148 standard "Systems and software engineering —Life cycle processes — Requirements engineering" superseded IEEE 830 in 2011.<ref name=":0" />  The current revision is from 2018.  This standard is broader as it covers also requirement quality criteria, requirement management processes, and business requirement specification (BRS), as well as stakeholder requirement specification (StRS).<ref name=":1">{{Cite web |title=ISO/IEC/IEEE 29148:2018 |url=https://www.iso.org/standard/72089.html |access-date=2024-12-30 |website=ISO |language=en}}</ref>  It proposes a slightly changed example structure.
