|IEEE software life cycle|
The ISO/IEC 15288 is a systems engineering standard covering processes and lifecycle stages. Initial planning for the ISO/IEC 15288:2002(E) standard started in 1994 when the need for a common systems engineering process framework was recognized. The previously accepted standard MIL STD 499A (1974) was cancelled after a memo from SECDEF prohibited the use of most United States Military Standards without a waiver. The first edition was issued on 1 November 2002. Stuart Arnold was the editor and Harold Lawson was the architect of the standard. In 2004 this standard was adopted as IEEE 15288. ISO/IEC 15288 has been updated 1 February 2008 as well as on 15 May 2015.
ISO/IEC 15288 is managed by ISO/IEC JTC1/SC7, which is the ISO committee responsible for developing ISO standards in the area of Software and Systems Engineering. ISO/IEC 15288 is part of the SC 7 Integrated set of Standards, and other standards in this domain include:
The standard defines processes divided into four categories:
Each process is defined by a purpose, outcomes, and activities. ISO 15288 comprises 25 processes which have 123 outcomes derived from 403 activities.
Example life cycle stages described in the document are: concept, development, production, utilisation, support, and retirement. However, these stages are not normative; the standard defines processes, not stages.
