Understanding individual parts of a system as well as how these parts interact to produce a whole describes which theory?

The concept of understanding individual parts of a system alongside their interactions to create a cohesive whole aligns precisely with Systems Thinking Theory. This theory emphasizes the interconnectedness of components within a system, illustrating that changes or functions in one part can significantly affect the others. Systems Thinking promotes the idea that to comprehend a complex system fully, one must look beyond isolated incidents and instead observe how multiple elements work collaboratively to achieve outcomes, thus fostering a deeper understanding of organizational and systemic dynamics.

While Systems Theory encompasses similar ideas about components and interactions, it may not fully emphasize the cognitive approach that Systems Thinking entails. The other options, including Biopsychosocial Theory and Holistic Theory, each focus on distinct aspects of healthcare and human behavior but do not address the overarching framework of understanding systems and their interactions in the same comprehensive way that Systems Thinking Theory does.
