3Frameworks

Framework

Are CI/CD pipeline failures driving failures?

Is test coverage insufficient to catch regressions?

Unit test coverage: 48% (target: 80%)

Integration tests added for only 22% of new endpoints

Is environment parity between staging and prod broken?

Config drift detected in 14 of 38 services (37%)

Staging DB uses v14.2, prod uses v14.8 — schema divergence

Are release process failures the root cause?

Are unapproved changes bypassing change management?

55% of post-mortem incidents traced to unapproved hotfixes

Change freeze violations: 8 in last 90 days

Is rollback capability too slow to limit blast radius?

Mean rollback time: 47 min (SLA: 10 min)

6 of 18 services lack automated rollback scripts

Is infrastructure reliability causing deployment failures?

Are stale dependencies creating compatibility failures?

42% of services running EOL dependencies (>18 months old)

3 critical CVEs in prod introduced in last 60 days

Is Terraform configuration drift causing infra failures?

8 IaC drift incidents/month detected via Terraform plan

Manual changes applied directly to 9 prod resources (bypassing IaC)
