Principles of management are not:

Absolute

The principles of management are not rigid prescriptions, which have to be followed absolutely. They are flexible and can be modified by the manager when the situation so demands. They give the manager enough discretion to do so. For example, the degree of concentration of authority (centralisation) or its dispersal (decentralisation) will depend upon the situations and circumstances of each enterprise. Moreover individual principles are like different tools serving different purposes, the manager has to decide which tool to use under what circumstances.
