WHAT IT IS
Several reference models exist: Gartner's Marketing Organizational Maturity, Forrester's B2B Marketing Automation maturity, BCG's Digital Acceleration Index, McKinsey's MOM (Marketing Operations Maturity). NUUN Digital's grid combines these with additions for AI-readiness and revenue accountability, scoring on five levels (Ad hoc, Developing, Defined, Managed, Optimized).
HOW IT WORKS
A good maturity assessment is evidence-based — not self-assessed — drawing on stack audits, content inventories, measurement reviews, and stakeholder interviews. Outputs are prioritized: where the gap is largest and the payoff is highest, plus the sequence dependencies that force order.
WHEN TO USE
Run a maturity assessment at the start of a CMO tenure, when a transformation investment is being sized, before a major re-platforming decision, or when a board asks for evidence the marketing function is earning its budget.
