I know that FogBugz help gives the following as a typical priorities scheme :
- Life or death emergency... the roof is actually on fire. Drop everything and fix.
- A customer is waiting for this
- Very important
- Important
- Not so important - fix if time
- Probably won't fix but worth remembering
- Do not fix
...but I'm wondering how others have named these, especially any that are perhaps more concise? I can't imagine #1 actually being "Life or death emergency... the roof is actually on fire. Drop everything and fix." but maybe rather "Emergency." [?]
