The diagram or chart that shows how a company or business is organized is called a/an ____________.

The term that describes a diagram or chart depicting the structure and organization of a company or business is "Organization Chart." This type of chart illustrates the relationship between different positions within the organization, including the hierarchy of control, roles, and responsibilities. It helps in visualizing how various departments and employee functions interconnect within the larger structure of the organization.

An organization chart typically includes various elements such as departments, individual roles, reporting relationships, and can even highlight different levels of management. This clarity is essential for employees to understand reporting lines and for management to define roles and responsibilities clearly.

While a flowchart helps in mapping out processes and workflows, or a hierarchy chart could imply levels within a system, it is the organization chart that specifically focuses on the layout of an organization's staffing and hierarchy. A structure map might generally refer to outlining frameworks but does not specifically capture the organizational relationships and hierarchy as an organization chart does, which is why the selected response is the most accurate in this context.
