For example, an organization
would choose to attain Level 2 (by satisfying the goals for each process area
in Level 2) before trying to undertake process areas in Levels 3, 4, or 5. Each level
provides the foundation for further improvements. This model begins with basic
management practices and continues with increasingly sophisticated focus areas
that belong within a specific level. Practices reside within process areas within levels.
There are five maturity levels, each serving as process boundaries.
The Staged approach provides guidance to organizations on the order of
improvement activities they should undertake, based on (key) process areas at each
stage/maturity level. Performing practices in the appropriate process area at a given
level will help stabilize projects, thus allowing the execution of further improvement
activities. Incremental improvement is supported in each maturity level/stage
because that stage contains a collection of process areas on which to focus current
activities.
The Continuous Representation (The Architecture
in Use by the Systems Engineering Models)
This structure focuses process improvement on actions to be completed within process
areas.
