Role Motivation Theories is concerned with four types of organisations and what makes them work. The four are not exhaustive of all possible organisational types but they do represent the major forms found in the world today. If we wish to understand organisational functioning in modern society then we need to have substantial insight into these four types of organisations. Drawing upon many years of research, John B. Miner argues that the organisational effectiveness required to produce high levels of productivity results from achieving a state of integration between the type of organizatonal system and the kind of people who fill the key positions in the system. Role Motivation Theores is the most comprehensive and up-to-date treatment of this work available.
