There was a formula from an agile seminar I can never remember where you take the average time to fix bugs, rate of incoming bugs and end up with a timeframe. Any bugs hanging around longer than this timeframe are WONTFIX by definition, because the incoming rate of more important bugs multiplied by your velocity means you will never get around to it. So when a bug gets into that list it means one of a) Its been badly prioritized and you dropped it on the floor b) It will only be fixed by accident, such as becoming irrelevant or c) You're screwed. Or something like that. Anyone remember? I think my notes are buried in a box somewhere (Damn paper notes! How last millennium!)
I think that was our collective Lean course. Mr. Poppendieck gave me a brief version of this advice in private conversation when I brought up the problem, but I think it subsequently also came up as course material. It was a real eye-opener.
Ironically, it was the week before we had a very similar discussion to the incumbent one, where management insisted that a particular page be driven down to zero timeouts, which we said was asymptotically impossible. It was eventually resolved with bigger hardware. On a sidenote, Stuart, thanks for being the voice of reason that day!
