Whatever... Once you've fixed the immediate issue then:
- Root-cause analysis.
- Determine the cost of incident.
- Estimate probability of it occurring again.
- Identify options to avoid in the future.
- Cost these options.
- Weigh the cost v benefit to see if anything should be done about it.
And do it efficiently! Start with ballpark estimates and rules-of-thumb to see if the arguments have any merit before getting bogged down in the detail (but make these assumptions clear when you explain it to the boss!).
