Change management

Goal

Apply production changes with predictability, reversibility, and clear communication.

Change cycle

1. 11) Classify change

   Define low-risk, high-risk, or breaking, and list impacted teams.

2. 22) Prepare validation

   Ensure tests, rollback criteria, and explicit execution owner.

3. 33) Execute in proper window

   Avoid external risk windows and confirm on-call coverage.

4. 44) Verify post-release

   Monitor core metrics and close only after sustained stability.

Decision matrix

Relationship with changelog

Every production change should include changelog context with:

• release timestamp;
• expected impact;
• mitigation path if needed.
