Show answer & explanation
Correct answer: C
Concept
The staged Capability Maturity Model is cumulative. To be rated at a maturity level, an organization must satisfy the goals of the key process areas at that level and at every lower maturity level.
Application
Level 4 key process areas therefore remain satisfied when a process reaches level 5, because level 5 builds on the practices established through levels 2, 3, and 4.
Contrast
CMM level 2 establishes repeatable project-management discipline; it does not yet include the level 4 key process areas.
CMM level 3 establishes defined organization-wide processes; it also precedes level 4.
CMM level 5 is the next higher maturity level and retains the requirements achieved at level 4.
The grouped choice CMM levels 2, 3, and 5 includes levels 2 and 3, which are below level 4 and therefore do not themselves satisfy level 4 key process areas.
Cross-check
The maturity sequence is Initial → Repeatable → Defined → Managed → Optimizing. Since progression is cumulative, the higher level immediately above Managed is Optimizing, namely CMM level 5.
