Establish Life-Cycle Model Descriptions

• Select life-cycle models based on the needs of projects and the organization. For example, in the case of a development project, project life-cycle models include:
  • Waterfall
  • Spiral
  • Evolutionary
  • Incremental
  • Iterative

  Examples of project characteristics that could affect the project life-cycle models include the Size of the project, experience and familiarity of project staff in implementing the process and constraints such as cycle time and acceptable defect levels

• Document the descriptions of the life-cycle models.
• Conduct peer reviews on the life-cycle models.
• Revise the descriptions of the life-cycle models as necessary.
