Context

A third party delivered cloud infrastructure ready to provision.

Tension

Several resource choices would become difficult or impossible to change after creation.

Scope

Formal architecture conformity assessment with explicit scales, blockers classified by irreversibility, named owners, environment gates, waivers and a one-page ratification.

Governance

Findings were raised against both the supplier and the programme itself. Severity alone was treated as insufficient: reversibility is what changes the governance response.

Result

The programme established a stop line before cluster creation and assigned owners to the irreversible blockers.

Lessons

Governance without authority, evidence and gates is ceremony. An instrument is what lets a review stop something.
