Life Cycle Terms and Concepts
Lead Authors: Mike Yokell Contributing Authors: David Endler, Garry Roedler
A life cycle is the evolution of a system, product, service, project or other human-made entity from conception through retirement. (ISO/IEC/IEEE 24748-1:2024) It can be helpful to create models to depict and manage the progression of the entity from beginning to end. These models are called life cycle models. A stage is a period within the life cycle of an entity that relates to the state of its description or realization. Stages relate to major progress, achievement milestones, or decision points of the entity through its life cycle. Technical reviews and audits are a mechanism by which sufficiently independent and knowledgeable stakeholders analyze the current state of a system, work product, or set of work products using pre-established criteria.
