Ran a "lessons learned" session today for a project that failed. we identified all the lessons. they were the same lessons from the last failed project.
I checked. literally pulled up the doc from the previous one. Eight of the twelve "key lessons" were word-for-word identical. different project, different team, same lessons.
So either we're really bad at learning, or the lessons-learned format produces a kind of output that doesn't actually translate into different behavior next time. I'm starting to think it's the second one.
We go through the motions. We write the doc. We file it in the same folder as the last one. nothing about how we plan the next project actually changes because the doc isn't read by anyone making the planning decisions.
Does anyone run retros in a way that the next project actually inherits something from them. not asking rhetorically. genuinely don't know what that looks like.
