Analysis 101: What is a System?
The document explains the concept of systems and their components, emphasizing that a system is an integrated whole made up of interdependent elements rather than mere hardware or applications. It highlights the importance of understanding both the structure (statics) and behavior (dynamics) of systems in various contexts, including enterprises and natural ecosystems. Additionally, it introduces systems thinking as a problem-solving approach that views issues within the context of the overall system.
