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

Lifecycle models may 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 the phases of the project. Also, the organization may define different lifecycle models for each type of product and service it delivers.
