Using Maturity Models in Practice
A maturity assessment typically involves: reviewing existing governance documentation, interviewing key stakeholders, assessing governance processes against the model's criteria, and scoring each capability area. The result is a maturity profile — a view of current maturity across all governance dimensions — and a gap analysis that identifies the most important areas for improvement.
CDMP Exam Relevance
Maturity models appear in CDMP questions about governance programme design and improvement planning. Key exam topics: the five maturity levels and their characteristics, the use of maturity models for assessment and roadmap development, and the principle that governance maturity must be built incrementally. The CDMP exam tests whether candidates understand that jumping maturity levels is not possible — each level must be built on the foundation of the previous one.
