MTTR: lower isn’t always better

MTTR (Mean Time To Recover) is a useful operational metric to track, but it doesn't always tell the whole story. It's only an average and doesn't take into account the total amount of downtime.

Lowering MTTR may be a good strategy in certain situations, but it's not always the right strategy. The goal should be to minimize downtime and noise, not just MTTR. It's important to consider the whole picture and not be misled by intuition when making decisions.
