Abstract
In 1966, Leavitt said: "Motivation is so much in the spotlight these days that some of us have come to believe motivation is management." This quotation proves that motivation has been a very important notion and has been taken into account by firms for a long time. What does motivation really means? The term motivation derives from the Latin word: movere which means to move. Thus motivation for us refers first to: "what energizes human behaviour, what directs or channels such behaviour"1 and "how this behaviour is maintained or sustained"1. Thus there is implicitly the notion of a goal that drives our strengths; indeed their behaviour is oriented towards something. Thus, motivation has been a concern for management in enterprises for a long time. In the first two decades of the twentieth century, motivation concerns were studied by engineers, as the famous Taylor for example. Their theory was that motivation was money driven.
