Scored on more than whether it worked
Two engineers can both restore the service. One took forty minutes and three risky actions to get there. The score says so.
Technical accuracy
Whether the system actually works again, verified by the environment itself.
Time to diagnosis
How long until the actual cause was identified.
Time to recovery
How long until service was restored for users.
Safety of actions
Whether the steps taken risked data, availability or a wider outage.
Unnecessary actions
Changes made that had no bearing on the problem.
Root cause understanding
Whether the cause was identified rather than the symptom suppressed.
These roll up into a readiness score as your history grows.
