Hi!
and "high"? The reason that I ask is that a median age of 738 days for "high" priority tasks seems very long. I would hope that we would not take two years to complete "high" priority tasks.
The median age of open priority X tasks is not the same as the median time it takes to complete priority X tasks.
Yes, it looks more the case of "we thought it's a high priority task but turned out it's not" rather than "we take a long time to do high priority tasks". I.e. maybe we need to have some rules around removing tasks from "High" if it's clear we're not doing it anytime soon.
