  • A system is a set of detailed methods, procedures, and routines established to carry out a specific activity, perform a duty, or solve a problem.

Structure

• It is an organized, purposeful structure consisting of interrelated and interdependent elements (e.g., components, entities, factors, members, parts). These elements influence one another to maintain the system’s activity and existence to achieve its goals.

Characteristics:

• Inputs, outputs, and feedback mechanisms.
• Homeostasis: Maintaining an internal steady-state despite external changes.
• Emergent Properties: The system displays properties unique to the whole that are not possessed by individual elements.
• Boundaries: Defined by the system observer, distinguishing the system from its environment.
