Rollback Principle

Created Nov 9, 2026, 1:18 AM · Updated Nov 9, 2026, 1:18 AM

Restore the last good state before you push - when the new state breaks, revert first, debug second.

Key Concept

  • If I cannot explain the path back in one sentence, I am not ready to ship.
  • Reversibility is the decision frame; rollback is the rehearsed move.
  • Last quarter I kept a bad Friday deploy live because I wanted the milestone more than the rollback conversation.
  • The team needed “my call, here is the fix,” not a speech.

Level 1 - Recognize

The rollback principle is the rule that you restore the last good state before you debug the broken one.

Level 2 - Explain

If you cannot say in one sentence how to undo a change, you are not ready to release it yet.

Level 3 - Use

Revert the bad Friday deploy in standup, say your call, fix Monday - rollback first, root-cause second.

Level 4 - Connect

Because production surprises are guaranteed, rollback clarity is readiness, not pessimism.

Level 5 - Create

Pair with Reversibility and Safety by Design - rehearse the undo drill before milestone pride blocks the revert.

Examples

  • Bad Friday deploy - glad I reverted in standup before pride kept the broken build live; said my call, fixed Monday.
  • The point guard ran Tuesday's inbound at half when the new play bled points - glad the old drill was already walked.
