Definitions notwithstanding, I tend to prefer the term 'AAR' (After Action Report). I had a manager in an early campus IT job that had been in the Marines, and he enforced a strict mandatory-AAR policy for anything even remotely complex.

It's really a fantastic idea and something I fully intend to use in every capacity that makes sense going forward. It doesn't make much sense as part of the software design flow, but it absolutely could (and probably should) be a tool in any deployment protocol.

My AARs usually read pretty much like this blog post, more or less to the T, although we emphasized what we would do differently in the future more.
