Status meetings and postmortems: "I once attended a project’s postmortem meeting in which the developers claimed that the system’s architect had given them an inconsistent and incomplete interface definition for the component they were supposed to write. Now, since a postmortem meeting (which is sometimes referred to as a lessons learned meeting) should result in some lessons, it was decided that in future projects the architect should pay closer attention to details, and the interface definition should be reviewed. Wow! What a lesson."
