This is underrated for managers and leaders trying to develop young talent. The takeaways:

  - With a system outage, don't lose your cool. Rationality is what's needed at the time.
  - Elevating "perfection" at the expense of potential breakage will ensure nothing ever moves forward and your team doesn't grow.

Some might believe that a serious ass-chewing is needed in this scenario; that would be a decision that's simple, quick and stupid. An emotionally-charged ass-chewing is almost always a sign of weakness in the ass-chewer. The only thing anyone ever learned about a beating is how to avoid it in the future.

Instead, this manager leaves his engineer with thoughts about how to avoid that problem in the future. Always remember -- an outage is eventually fixed, but a damaged relationship continues forward.
