One issue is the need to retain the knowledge of retirees. Of course the fact that the baby boomer bulge is now reaching retirement age is making this issue particularly salient. KM techniques are very relevant to this issue. One technique is the application of the lessons learned idea—just treat the retiree’s career as a long project that is coming to its end and create an after action report, a massive data dump. This idea seems obvious, but only in special cases is it likely to be very useful.
