A) Mathematical Theory—It is also known as Quantitative Approach Theory or Operational Research Theory or Management Science Theory. The management scientists led by operation researches and system analysts see management as a "system of mathematical models and processes." They hold that since managing is a logical and rational process, it can be expressed in terms of mathematical relationships and models. Its basic assumption is that an organisation is a system with its parts in interaction al and interdependent relationships and these interactions and interdependencies can be expressed in terms of models and equations. The main features of the mathematical school of thought are: (1)Management is concerned with problem-solving and it should use mathematical tools and techniques for this purpose. (2)The different factors involved in management can be expressed in the form of models or equations which can be solved with the help of mathematical techniques. (3) Management problems can be described in mathematical symbols. (4) The basic methodologies may be operations research, mathematical tools, simulation and model building. The main contributors to this thought are Taylor, Gilbreth, Gantt, Joel Dean, Newmann, Ackoff and Hicks. There is no doubt that management science has made significant contributions by applying mathematical tools to the solutions of various complex problems of management. But mathematical techniques cannot be considered as a substitute for management. Mathematics is at best a tool in management study and not coterminous with management. (B) System Approach Theory-The theory was developed by Boulding, Rosen, Johnson. Henderson, Daniel Katz, C.W. Churchman etc. A system is a set of inter-connected and inter-related elements directed to achieve certain goals. This theory views organisation as an organic and open system composed of many sub-systems. As a system organisation is composed of a number of sub-systems viz. production, supportive, maintenance, adaptive managerial, individuals and informal groups. All these sub-systems operate in an interdependent and interaction al relationship. The various subsystems or parts of an organisation are linked with each other through communication, decisions, authority responsibility relationships, objectives, policies, procedures and other aspects of coordinating mechanism. Organisations as systems have a variety of goals. The important among them are survival, integration and adaptation with environment and growth. The major features of the approach to the study of management may be summed up as under: (1) A system consists of inter-related and interdependent parts. (2) The approach emphasises the study of the various parts in their inter-relationships rather than in isolation from each other. (3) The approach brings out the complexity of a real life management problem much more sharply than any of other approaches. (4) The approach may be utilised by any of the other approaches. (5) The approach has been utilised in studying the function of complex organisations and has been utilised as the base for new kinds of organisation. The Systems Approach has an edge over the other approaches insofar as its closeness to reality is concerned. However the problem with the approach is its utter complexity particularly when it comes to a study of large and complex organisations. The conceptual framework of management provided by this approach is too abstract to be useful to practising managers. The approach recognises the input of environment but does not functionally relate it to management concepts and techniques. © Contingency Approach Theory—Contingency theory has been developed mainly during 1970s. The major contributors to this school of thought in management are Joan Woodward, Fiedler, Lorsh, Lawrence etc. Theorists of all other approaches to management have not integrated the environment. They often assume that their approaches and systems have universal applicability. The contingency approach incorporates the environment and attempts to bridge the theory practice gap. Contingency theory builds on the major premises of the systems. Theory that organisation is organicand open system and there is a relationship of interdependence between an organisation and its environment, as well as within and between its various sub-systems. The contingency theory aims at integrating theory with practice in a systems framework. According to this approach, management is situational. This approach rejects the universality of management thesis. Managers should design organisations, define objectives and formulate policies and plans according to the prevailing environmental conditions. Managerial policies and plans must respond to changes in environmental conditions. Further, management should have sufficient skills to anticipate and comprehend environmental changes, and to accommodate change. Finally, it should use the contingency model in designing the organisation developing its information and communication system, adopting effective leadership styles and formulating suitable objectives, policies and practices. Thus, this approach provides a method of analysis as well as a way of integrating organisation with its environment. A contingency approach seems to hold a great deal or promise for the future development of management theory and practice. The other approaches to management can all be in-corporates into the contingency framework. At present, the contingency approach seems to be the only practicable way to studying management. It adequately clears the nature of management. Hence it is the best approach of all.
