My comment wasn't intended personally; your words about "will never recur" just reminded me of this peculiarity of software systems, where it's often error handling/monitoring/backups/etc. that cause cascading failures in the systems they're intended to safeguard.

I'm sorry if I misconstrued your meaning, but I am flattered that you think there are things beneath me!

Fair enough. I see the whole function of a postmortem in a very simple way: to avoid recurrence of the same fault. Yes, there will be plenty of new ones to make. But if you don't change your processes as the result of a failure you are almost certainly going to see a repeat because the bulk of the conditions are still the same. All it takes then is a minor regression and you're back to where you were before. This I've seen many times in practice and I suspect that Colin isn't immune to it. And yes, I look up to you, your writing is usually sharp and on point and has both amused me and educated me. So you have an image to live up to ;)
