Goals for post-incident improvement

How might we have detected the problem faster? Preferably before our users do.

How might we have diagnosed the problem faster? See observability.

How might we have contained the problem faster? See containment vs countermeasure.

How might we have reduced the impact of the problem? For example, see staged rollout.

How might we have prevented the problem?
