What term describes a verbal or graphical explanation for how a system works or is organized?

The term that describes a verbal or graphical explanation for how a system works or is organized is the conceptual model. A conceptual model serves as an abstract representation of a system, illustrating its components and their relationships in a way that is easily understandable. This type of model focuses on how the various parts of a system interact and function together, rather than on specific details or technical implementation.

Conceptual models are foundational in many fields, as they help to clarify complex ideas, making it easier for stakeholders to grasp how a system operates. They can use both textual descriptions and graphic representations to encapsulate the fundamental principles that govern a system.

Other terms mentioned, such as flowcharts, system diagrams, and organizational charts, each serve different specific purposes. For instance, flowcharts visualize processes step by step; system diagrams provide a more detailed view of interactions within a system; and organizational charts outline the hierarchical structure of an organization. While these are useful tools, they do not encompass the broader and more theoretical nature of a conceptual model in representing how systems are organized or function.
