What it is for
Use the ten questions to make uncertainty around ownership, authority, DNS, email trust, dependencies, change and incident readiness explicit enough to govern.
Board, executive and risk preparation; incident review; supplier assurance; and recurring domain-governance review.
A Baseline Review Summary of priorities, evidence needs and practical next actions - not a score or assurance report.
Version 1.0 keeps the ten canonical questions stable enough to cite and reuse while supporting material improves through evidence from real use.
