Repeatable dev/staging/prod environments for a growing team
How a UK product team eliminated environment drift, cut engineer onboarding from 2 days to 20 minutes, and reduced config-drift production incidents to zero.
← All case studies
The problem
- Dev and staging environments drifted from production — bugs only appeared in prod
- Infrastructure changes were applied manually with no review trail or audit log
- Onboarding a new engineer took 2–3 days of environment setup and tribal knowledge
- Two production incidents in 3 months caused directly by config drift
What we delivered
- Dev, staging, and prod environments defined as code with a single source of truth
- Plan / review / apply change workflow — no infrastructure changes without a PR
- Standardised access roles and secrets management pattern
- Architecture diagram, runbook, and team walkthrough on handoff
Results
Environment setup time
2 days → 20 min
Config drift incidents
2 per quarter → 0
Infra changes reviewed
0% → 100%
How it worked
- Understand — audited each environment, mapped differences, and identified the drift sources
- Define Done — agreed acceptance criteria: parity across environments, reviewed change workflow, onboarding checklist
- Implement — incremental migration, each environment converted with team visibility at every step
- Handoff — full docs, architecture diagram, runbook, team owns the setup
