I wish as much attention was paid to perform post mortems regularly then to only do estimation. You know, actually look at "hey, this is what we guessed and this is what actually happened".
I've had to fight to actually hold post mortems, and every time I've done this, the manager ends up asking, "hey, can I share this?"
So clearly, there's value, at least when we've done them.
I'm amazed at how few places even perform a complete feedback loop. It's just, "when can you get this done?" and, "is it done yet?".
To tie this a bit more into the actual article: It might be even more accurate to just ask people in a post mortem for some feedback, instead of trying to build some data set based on estimates and SLOC. Like an exit poll.
