Governance leaders have a narrow window to prove that governance fuels progress, not bureaucracy. Whether you’re building from zero or evolving a partial setup, the first 90 days are crucial to define a mandate, activate ownership, and deliver visible wins.

It draws on Forrester’s governance model to help you productize governance, activate metadata, and align to outcomes like privacy, compliance, and self-service.
