Systems approach in management:
A system is a collection of parts or subsystems that operate interdependently to achieve the goal of the entire system. It sees the whole system rather than examining separate variable of the organization.
The system analyses and study management by putting its parts together and assuming that the whole is greater than the sum of its parts. Also a study of separate parts of the system cannot give a correct picture of the whole system.
A management system or an organizational system constitutes a relationship between parts of its system, but it also depends upon the outside environment for feedback and resources.
