System Theory A system is a set of interconnected and inter-related elements of management activity. It is an arrangement of components of activities performed for achieving certain objectives. Thus, a system has three components: arrangement, objectives and a plan. The arrangement is designed and planned in an effective manner to achieve the objective. Men, materials and money are planned to achieve the objectives of the organization. Recently, it has been agreed that the organization is a system wherein operation, marketing, finance, etc. are subsystems. The modern organization theory believes in the General Systems Theory (GST) which is applicable to all scientific phenomena. Kenneth and Boulding have contributed a systems theory to establish to single, self-contained and generalized theory for particular disciplines. The system approach believes in a static structure and a dynamic and cybernetic system. It has increased mobility, technological behavior, self-awareness and the goal-directed approach. The system is an organization wherein the various components are subsystems which are managed and mobilized for attaining the organizational goals. It is an interconnected, interdependent and interacting arrangement of men and materials. For example, business is a social technical system, a plant is a botanical system, and a car is a mechanical system and so on. MBA - Knowledge base
