- D: Correct.

- A: Correct.
- B: Official status does not prove currency.
- C: Staleness does not prove Level 0/no capability.

C15-042
Correct: B — Maturity improvement changes processes, methods, tools, roles, behaviors, and culture; it therefore needs governance, shared vision, communication, measurement, and organizational change.
- A: A score cannot create adoption without capability change.
- B: Correct.
- C: Framework change alone does not solve resistance.
- D: A larger tool inventory does not create cultural adoption.

C15-043
Correct: C — A DMMA rating is the capability snapshot at a point in time.
- A: Rate of change is trend over time.
- B: Resource utilization measures human effort/cost.
- C: Correct.
- D: Spend management addresses cost allocation/value.

C15-044
Correct: D — Rate of change measures how quickly maturity capability improves relative to baseline through periodic reassessment.
- A: Interview speed is not this metric.
- B: That is data volatility, not maturity movement.
- C: Vendor release cadence is unrelated.
- D: Correct.

C15-045
Correct: A — Resource-utilization metrics reveal human effort/capacity cost, such as staff time manually aggregating or reconciling data.
- A: Correct.
- B: Ratings describe capability but not direct labor cost.
- C: Input counts describe assessment coverage.
- D: Level names are classifications, not cost measures.

C15-046
Correct: B — Changed scope/input coverage can make the apparent improvement non-comparable with baseline.
- A: Score direction alone is insufficient evidence of progress.
- B: Correct.
- C: Scope can change, but interpretation must account for the difference; reassessment is not automatically discarded.
- D: Unqualified rate calculation can mislead.

C15-047
Correct: C — Chapter 15 uses readiness for automation as an example of risk exposure relative to current maturity/capability.
- A: Input count addresses coverage, not operational risk.
- B: Spend can matter but is not the strongest clue.
- C: Correct.
- D: Number of criteria does not answer capability risk.

C15-048
Correct: D — DMMA input metrics show the completeness, depth, and scope behind a score so users know what evidence the rating represents.
- A: Input metrics complement rather than replace maturity ratings.
- B: Comparable trend still depends on methodology/scope, not input counts alone.
- C: Their purpose is broader than financial return.
- D: Correct.
