The significance of principles of management can be discussed in terms of the following points:
Providing managers with useful insights into reality: The principles of management provide the managers with useful insights into real world situations. Adherence to these principles will add to their knowledge, ability and understanding of managerial situations and circumstances.
Optimum utilisation of resources and effective administration: Resources both human and material available with the company are limited. They have to be put to optimum use. By optimum use we mean that the resources should be put to use in such a manner that they should give maximum benefit with minimum cost. Principles equip the managers to foresee the cause and effect relationships of their decisions and actions.
Scientific decisions: Decisions must be based on facts, thoughtful and justifiable in terms of the intended purposes. They must be timely, realistic and subject to measurement and evaluation. Management principles help in thoughtful decision-making. They emphasise logic rather than blind faith.
Meeting changing enviornment requirements: Although the principles are in the nature of general guidelines but they are modified and as such help managers to meet changing requirements of the environment. You have already studied that management principles are flexible to adapt to dynamic business environment. For example, management principles emphasise division of work and specialisation.
Fulfilling social responsibility: The increased awareness of the public, forces businesses especially limited companies to fulfill their social responsibilities. Management theory and management principles have also evolved in response to these demands.
Management training, Education and Research: Principles of management are at the core of management theory. As such these are used as a basis for management training, education and research.
