A system diagram is a visual representation of a system, showing the relationships and interactions between its components. It is a simple and high-level description of a system that exists or needs to be built. The diagram typically includes the components of a process, such as hardware, software, databases, and people involved, as well as the communication pathways between them. It can be used to understand, design, analyze, and document a process
. System diagrams are more than process flow charts; they include feedback loops and other factors that influence decision-making and interactions between components
. They are useful for understanding complex systems, such as the structure of a company, the functioning of a machine, the flow of information in a computer program, or the dynamics of a network of people
