OPD.SP 1.2 Establish Lifecycle Model Descriptions
Summary
Establish and maintain descriptions of lifecycle models approved for use in the organization.
Description
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 work. Also, the organization can define different lifecycle models for each type of product and service it delivers.
Example Work Products
- Descriptions of lifecycle models
Subpractices
1. Select lifecycle models based on the needs of work groups and the organization.
The selection of a service lifecycle model depends on the characteristics of the services and the environment. Some service providers define lifecycle phases based on their standard service definitions.
- Plan, define, enable, and measure
- Scope definition, planning, execution, and termination
- Strategy, design, transition, operation, and improvement
Often, individual service domains have implicit lifecycles associated with them that involve points of communication, evaluation, and decision. Descriptions of these points can be included in the set of descriptions of lifecycle models approved for use in the organization.
- Waterfall
- Spiral
- Evolutionary
- Incremental
- Iterative
2. Document descriptions of lifecycle models.
Lifecycle models can be documented as part of the organization’s standard process descriptions or they can be documented separately.
3. Conduct peer reviews on lifecycle models.
4. Revise the descriptions of lifecycle models as necessary.
