Carzo and Yanaozas identifies three sub-systems in an organisation as a systems approach, Which one is not the sub-system?

The correct answer is D. Power sub-system.

Carzo and Yanouzas identified three subsystems in an organization as a systems approach: technical, economic, and social.

The technical subsystem is concerned with the production of goods and services. It includes the physical plant, equipment, and technology used to produce goods and services.

The economic subsystem is concerned with the acquisition and use of resources. It includes the financial resources, human resources, and information resources used by the organization.

The social subsystem is concerned with the relationships among people in the organization. It includes the formal and informal communication networks, the power structure, and the culture of the organization.

The power subsystem is not one of the three subsystems identified by Carzo and Yanouzas. However, it is an important aspect of organizational structure and dynamics. The power subsystem is concerned with the distribution of power and influence in the organization. It includes the formal and informal power structures, the decision-making process, and the conflict resolution mechanisms.
