Bug prioritization framework/process

Hi everyone!

We're revamping our bug prioritization framework/process at the moment but have been struggling with a few key areas. Some of the specific question marks we have are:

• How do you flag bugs and track the number of occurrences?
  • Does CS or eng own the "number of users" impacted?
• How do you communicate with the product team as bugs are resolved or being worked on?
• What do you use as the various tiers of bugs? We currently are looking at % of users impacted but the numbers seem really high (i.e. 50-90% users impacted is currently the middle tier in terms of priority). 
  • Are there ways you tie the bug to current and future revenue?
• What resolution times benchmarks do you use?
• Do you have any shareable resources around how your org defines 'bugs'?

Would love to hear how others approach this and work with their eng teams to resolve issues!
