Before you can define where you're going, you need to be brutally honest about where you are.
Most organizations overestimate their Data maturity by one to two levels. This isn't self-deception, it's a natural result of measuring maturity against internal reference points rather than external benchmarks.

Level 1, Initial / Reactive

Don't turn your maturity assessment into a 6-month consulting engagement.
Week 1, Data Collection
Run structured interviews with 15-20 stakeholders: data owners in each major function, IT leads, analytics team leads, business unit heads. Use a standardized questionnaire covering the 11 DAMA-DMBOK knowledge areas: data governancedata governanceData governance is the set of policies, roles, and processes that ensure data is accurate, secure, well-defined, and used responsibly across an organization.View full definition →, data qualitydata qualityThe degree to which data is fit for purpose: accurate, complete, consistent, timely, valid and unique.

Based on CDO roundtables and published assessments across 500+ organizations, the consistent pattern: strong in Business Intelligence, weak in governance.

Definitions are inconsistent.
The consequence: analytics look sophisticated but aren't trusted. When the CFO's revenue number doesn't match the CMO's, everyone loses faith in data. The fix isn't more analytics tools. It's governance work first. It's boring, invisible, and the CDO's most important job.
