P1, P2,...P5 is a broken system: here's what we do instead

Software developers need to prioritize bugs when they are discovered, and most do this with an ordered priority scheme. Tracking tools like Jira provide a column on each ticket, and many organizations use numbers, such as P1, P2, P3, P4, and P5. Some even adopt a P0 as an indicator that there are some bugs that have an even higher priority than P1.
