Configuration Management (CM)

A process for establishing and maintaining consistence of baselines, approving and controlling changes, and recording and reporting changes in status of a product under development.

Configuration Management Plan (CMP)

A documented process for managing a system’s Configuration Items (CI) in a controlled way.

Configuration Status Accounting

A process for reporting information regarding the status of the established baseline and the proposed/ approved changes to that baseline.


A limitation placed on a system design by law, policy, physics, or other existing systems within which the solution must work.

Context Diagram

A diagram that depicts the boundary of an entity and the external entities that influence its behavior.

Continuous Opportunity Risk Management

An iterative, multi-step process to continually identify, define, handle, control, and communicate opportunities/ risks.
