Establish and maintain descriptions of lifecycle models approved for use in the organization.

Lifecycle models can be developed for a variety of customers or in a variety of situations, since one lifecycle model may not be appropriate for all situations. Lifecycle models are often used to define phases of the project. Also, the organization can define different lifecycle models for each type of product and service it delivers.

Lifecycle models describe acquisition lifecycles, depending on the acquisition strategy chosen. The acquisition lifecycle typically begins with the pre-award phase of a supplier agreement, continues through the phases of awarding and managing the supplier agreement, and ends when the supplier agreement period of performance ends, usually with the acceptance and completion of the warranty for the acquired product and the transition of the product to the support organization.
