> I'm confused by your comment. How did you decide this was something worthy of fixing if it "doesn't show any good metrics"? If you can't quantify the issue in any manner, how do you determine it's worth doing?

Because sometimes some things without metrics are incidental to the actual thing you set out to do.

E.g. a large refactor that switches libraries which is necessary for your new service that give 10% lower latency. But that library refactor will need to be done and it will take 2 months.
