The model-based method of Capability Evaluation (CE) has three styles of use.
Project monitoring, and specifically monitoring of Process Improvement (PI).
Internal assessment of its own processes by an enterprise (or part of an enterprise).
Contractor selection in major projects where quality in use has been identified as a risk area – Pre Contract Award Evaluation (PCAE).
The scope of an assessment (in terms of processes assessed) is tailored to the needs of the project. Similarly, the size of an assessment (in terms of organisations assessed) can be tailored to circumstances. It is possible to conduct very low effort assessments at the early stage of a project, on small projects and for informal process risk/PI purposes.
The diagram below shows how project risks and project requirements provide the inputs to a Process Risk Assessment, which is followed by Process Improvement action and tracking.
