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.
