Motivation has long been the topic of interest for both managers and organisational researchers. There are two primary reasons for this continued interest. First, motivation is an integral part of the performance equation at all levels. It is therefore an important topic to be understood for pragmatic reasons. Second, motivation is seen as the fundamental building block in the development of useful theories of effective management practice. It is indeed an important topic in many subfields in the study of management including leadership, managerial ethics, decision making and organisational change. It is not surprising, therefore, that this topic has received a lot of attention and generated many approaches toward understanding it.
