One of the things I wish I did more often and better is follow through with the data collected during a Postmortem. I'm looking for input on "How do you ensure the postmortem data is followed up and dealt with -after- the project is done and you have moved on to another project?"

Specifically, I'm looking for thoughts on "Is it the PM's job to ensure the postmortem is acted upon, or does that responsibility transition to owners of the individual items or to the functional management team?"

Thanks!
