Here is an interesting presentation on Knowledge Transfer. The author segregates people involved (roles/population) into five different categories:
- Innovators (2.5%)
- Early Adopters (13.5%)
- Early Majority (34%)
- Late Majority (34%)
- Laggards (16%)
Though this presentation is not from a typical Software Background, it does provide a good insight into how these aspects affect even the Software Industry.
Hope this presentation provokes you to identify the people with whom you interact on a regular basis, into the 5 categories, and aid you in adapting better way of instigating the project folks to get into the rut of proper Knowledge Transfer.
