In some sense, the most important source of knowledge is inside people's heads. You don't want an organization that's leakier than necessary. You don't want too many people cycling out. You need to set up team structures, so that the more experienced people teach the less experienced ones. This is going to become a bigger issue as we come up against large numbers of people retiring."  ¶ 09:20
