Systems approaches is a transdisciplinary framework or set of methodologies for studying complex entities or phenomena as interconnected wholes rather than isolated parts. It investigates the relationships, interactions, feedback loops, and emergent properties arising from the dynamic interplay between system components and their environment. Key characteristics include holism, attention to non-linear dynamics, and the consideration of system boundaries and context. Its significance lies in providing a comprehensive perspective essential for understanding complexity, predicting system behavior, and designing effective interventions across diverse academic and practical domains.
