What diagram visually represents the structure and hierarchy of an organization?

An organizational chart is the most effective tool for visually representing the structure and hierarchy of an organization. It provides a clear depiction of the relationships between different positions within the organization, illustrating the chain of command and how various roles interact with each other. This type of chart typically shows levels of management, departments, and employee roles, making it easy to understand how authority and responsibilities are distributed.

In contrast, other options serve different purposes. A flowchart is primarily used to represent processes or workflows, showcasing the steps involved in a particular task rather than organizational structure. A mind map is designed to organize information visually, allowing for brainstorming and idea generation, but it does not convey hierarchical relationships. A process map focuses specifically on detailing the steps of a process, similar to a flowchart, rather than illustrating organizational hierarchy. Thus, for capturing the structural dynamics of an organization, the organizational chart is the most apt choice.
