I'm not sure there is one model. The British Columbia government made a really fine attempt to try to make sense out of the appointments process and created a position within the premier's office that was responsible for gathering biographical data, identifying individuals, classifying the requirements for particular jobs, and criteria. It has worked very well, to my knowledge, at the provincial level. In fact, I confess to having consulted that individual within the premier's office on several occasions with regard to west coast appointments.
