Stop Approving Everything
A CAB that reviews every change is a CAB that rubber-stamps. Classify changes: standard (pre-approved), normal (CAB review), emergency (expedited). Only normal changes need full review.
Risk and Impact, Quantified
Assign risk and impact scores via questionnaire. Low-risk, low-impact normal changes can auto-route to a peer reviewer instead of full CAB. Define thresholds, don’t eyeball them.
Automated Gating
Wire approvals to real signals: code review status, test pass rate, change freeze windows, security sign-off for regulated workloads. Manual gates become automatic when conditions are met.
Emergency Change Without Chaos
Emergency changes happen. The goal isn’t to eliminate them — it’s to ensure they get the same post-change review as planned ones. A backlog of unreviewed emergency changes hides problems.
Measure Change Success Rate
Track: change success rate, unauthorized change count, rollback rate, mean time to implement. Publish weekly. A 95% success rate is respectable; dropping below 90% means your process or your testing is broken.
