DAMA-DMBOK2 Revised source boundary: Chapter 15, printed pp. 503–520
Study-system role: supporting / specialist context

Chapter 15 teaches how an organization turns a vague question — “How good are we at managing data?” — into a disciplined, evidence-supported improvement cycle.

The chapter is not mainly about producing a maturity number. It is about establishing a defensible current-state baseline, deciding what capability the business actually needs, translating the gap into a staged roadmap, governing the change, and measuring whether capability improves over time.

One mental model for the whole chapter

BUSINESS DRIVER → OBJECTIVE & SCOPE → FRAMEWORK → EVIDENCE → RATING & CONSENSUS → INTERPRET GAP → TARGET STATE → ROADMAP → GOVERN IMPROVEMENT → RE-ASSESS

A crucial boundary runs through that spine:

  • Assessment: establish and interpret the current state.
  • Improvement: execute the changes that move capability toward the target state.

Do not mix them. Fixing processes while evidence is still being gathered can change the state being measured and weaken comparability.

What to know cold

  • L0 No Capability → L1 Initial/Ad Hoc → L2 Repeatable → L3 Defined → L4 Managed → L5 Optimized.
  • Level ≠ criterion score. A 4/4 “Effective” item does not prove maturity Level 4.
  • Assessment dimensions: Activity, Tools, Standards, People/Resources.
  • Five DMMA activities: Plan → Assess → Interpret → Improve → Re-assess.
  • Participant opinion is an input; evidence-supported consensus is the objective.
  • Current state is where capability is now; target state is what the business needs.
  • Priority comes from business-relevant gap and risk, not lowest score alone.
  • A roadmap needs sequence, timing, expected capability movement, oversight, and measures.
  • Reassessment must protect comparability and track rate of change.
