IEEE 1220-2005

This standard defines the interdisciplinary tasks that are required throughout a system's life cycle to transform customer needs, requirements, and constraints into a system solution. This document is intended to guide the development of systems (which include humans, computers, and software) for commercial, government, military, and space applications. The information applies to an enterprise within an enterprise that is responsible for developing a product design and establishing the life cycle infrastructure needed to provide for life cycle sustainment. (Existing 1.2, Purpose): "The purpose of this document is to provide a standard for managing a system from initial concept through development, operations, and disposal. The inclusion of computers and associated software in today's products has made the need to engineer each of those products as a total system more acute. The human, physical, and software components should all be addressed to optimize overall system performance." The purpose of the revision project is to harmonize the standard with the new ISO/IEC 15288, System Life Cycle Processes. Revision Standard - Superseded. The interdisciplinary tasks that are required throughout a system's life cycle to transform stakeholder needs, requirements, and constraints into a system solution are defined. This standard is intended to guide the development of systems for commercial, government, military, and space applications. The information applies to a project within an enterprise that is responsible for developing a product design and establishing the life cycle infrastructure needed to provide for life cycle sustainment.
