P15289 - ISO/IEC/IEEE Draft International Standard -- Systems and Software Engineering -- Content of Life-Cycle Information Items (Documentation)
Project Details
This document specifies the purpose and content of all identified systems and software life-cycle and services information items (documentation). The information item contents are defined according to generic document types, as presented in Clause 7, and the specific purpose of the document (Clause 10). This document assumes an organization is performing life-cycle processes, or delivering services, using either ISO/IEC/IEEE 12207:2017, Systems and software engineering -- Software life cycle processes, or ISO/IEC/IEEE 15288:2015, Systems and software engineering -- System life cycle processes. This document provides a mapping of processes from the above standards to a set of information items. It provides a consistent approach to meeting the information and documentation requirements of systems and software engineering and life-cycle services. This document does not establish a service management system. ISO/IEC/IEEE 12207:2017 and ISO/IEC/IEEE 15288:2015 define a set of processes, identical in purpose and outcomes but with different activities and tasks, for managing and performing the stages of a software or system life cycle. They define an Information Management process, but do not detail information items in terms of name, format, explicit content, and recording media. The generic document types defined in this document are used to identify the information necessary to support the ISO/IEC/IEEE 12207:2017 and ISO/IEC/IEEE 15288:2015 agreement; organizational project-enabling, technical management, and technical processes. For each life-cycle process or service, it would be possible to prepare a policy, plan, procedures, and reports, as well as numerous records, requests, descriptions and specifications. Such an elaboration of the documentation schema would be more rigorous than specified by ISO/IEC/IEEE 15288:2015 or ISO/IEC 12207:2017. As ISO/IEC/IEEE 15288:2015 points out (1.4), "The users of this document are responsible for selecting a life cycle model for the project and mapping the processes, activities, and tasks in this document into that model. The parties are also responsible for selecting and applying appropriate methodologies, methods, models and techniques suitable for the project." Thus, information items are combined or subdivided consistent with the life cycle model, as needed for project or organizational purposes, as further defined in Clause 4, Applicability, and Clause 5, Conformance.
