Environments
The Technology department maintains three environment tiers for all systems. Each tier has specific purposes, access controls, and deployment policies.
Environment overview
| Environment | Purpose | Stability | Who can deploy | Data |
|---|---|---|---|---|
| Development | Active development, experimentation | Low — can break | Any developer | Synthetic / anonymized |
| Staging | QA, UAT, pre-production validation | Medium — should be stable | Squad lead approval | Production copy (anonymized) |
| Production | Live system serving end users | High — changes require change ticket | Change window + approval | Real data |
