Experienced members of project teams are familiar with the concept of lessons learned, or project "post mortems." These are the discussions that occur near the end or after the end of the project when everyone is ready to move on to something else, but decide to get together to compile a list of things they wished they would have done differently or things they found out during the project. The theory is that these lessons would be recorded for future project teams to read, study, and integrate into their projects.
