Roger C. Greer's Service Cycle Model




Robert Grover states, "A professional applies knowledge and specialized information that results in a specific service. The role of any professional—whether it be physician, librarian, teacher, or financial planner—is that of diagnosing needs, prescribing a service that meets those needs, implementing that service, and evaluating the outcome of this interaction." This interaction or cycle is represented in the following model by Roger C. Greer.
