Answer:
C. systems theory
Explanation:
Systems theory can be defined as a strategic framework which typically involves understanding the concepts and principles surrounding the relationship between various components of a system, rather than in isolation.
This ultimately implies that, when systems theory helps the management, systems engineer or managers to have a good understanding of the wholeness, integration, hierarchy, patterns, and relationships between components or departments found in an organization work together.
Hence, understanding how the components or departments of a hospital work together is a part of systems theory. Therefore, with systems theory we can identify which component or department would be affected by any change in another i.e the role each component or department plays.
