A recovery drill works best when it tests the things teams often assume will be obvious in the moment.
The best drill reveals what the team would forget during a real outage.
Field takeaways
- Practice the handoff from detection to recovery.
- Test spare access and documentation during the drill.
- Measure how long it takes to get back to stable operations.
Test the first ten minutes
The earliest part of the recovery path matters most because confusion is highest there. The drill should show whether the right people are contacted quickly and whether the next step is obvious.
- Spare verification
- Access permissions
- Recovery sequence
Include access to the things that matter
A drill that skips spare parts, logbooks, or permissions is not a full drill. Recovery depends on whether the team can reach the needed materials and evidence quickly.
Measure time to stable, not just time to start
The most useful drill metric is how quickly the site returns to a stable operating posture. That gives the team a practical number to improve on next time.
