Data governance — DAMA-DMBOK
How do you place an organization's data management maturity, area by area, with the DAMA-DMBOK framework?
At a glance
- Scale from 0 to 5.
- 11 areas assessed separately.
- Assess with evidence, set a target per area.

Why this matrix matters in my field#
The DMBOK2 is the profession's reference for vocabulary: it sets what “managing data” covers. Its maturity grid lets you say, area by area, where you stand — governance, modeling, quality, metadata, integration, security, data warehousing and BI. For anyone designing decision-support platforms, it is the framework that links the technical side (model, pipeline, warehouse) to the organizational side (roles, policies, quality).
The maturity scale#
The DMBOK2 assessment relies on a six-level scale, in the spirit of CMMI. The wording below is a synthesis; the exact titles and their criteria should be checked in the book.
No capability#
No recognizable practice in the area.
Initial (Initial / ad hoc)#
Ad hoc, person-dependent responses. Little or no documentation; successes are not repeatable.
Repeatable#
Minimal processes exist and are followed in some teams; repeatability still depends on local discipline.
Defined#
Processes, standards and roles are formalized and applied consistently across the organization.
Managed#
Processes are measured and driven by indicators; deviations trigger action.
Optimized#
Continuous improvement is tooled and automated; processes evolve based on measurements.
The dimensions assessed#
The 11 DMBOK2 knowledge areas; each area can be assessed at its own level.
Data Governance#
Decisions, roles, policies and accountabilities around data; at the center of the framework.
Data Architecture#
Blueprint and overall structures of the organization's data.
Data Modeling and Design#
Conceptual, logical and physical models; reasoned normalization and denormalization.
Data Storage and Operations#
Databases, administration, availability, performance, backups.
Data Security#
Confidentiality, integrity, availability, access and compliance.
Data Integration and Interoperability#
Moving, consolidating and exchanging data between systems.
Document and Content Management#
Unstructured data: documents, content, life cycle.
Reference and Master Data#
Shared reference data, single identity of entities, quality of master data.
Data Warehousing and Business Intelligence#
Warehousing, reporting and decision-support analysis.
Metadata#
Glossaries, catalogs, dictionaries, lineage.
Data Quality#
Defining, measuring and improving quality according to uses.
How to use it#
- Choose the scope: the whole organization, a division, a data product.
- For each area, collect evidence (documents, dashboards, logs, interviews), not impressions.
- Assign a level per area; avoid computing a single average that would hide the gaps.
- Set a target per area, justified by a business stake or a risk.
- Plan stages and reassess at regular intervals.
Limitations and precautions#
- A high level is not a universal goal: aiming for “Optimized” everywhere is rarely cost-effective.
- The grid measures organizational capabilities, not the quality of a given dataset.
- Self-assessment tends to be optimistic; see the Dunning-Kruger effect.
- Level names may vary from one edition or adaptation to another: always cite the edition used.
