What is the primary use of organizational charts?

The primary use of organizational charts is to illustrate a hierarchy within an organization. These charts provide a visual representation of the various levels of authority and responsibility within the business, showing how various positions are linked and who reports to whom. This clear depiction helps employees and stakeholders understand the structure of the organization, facilitating better communication and collaboration.

While other options represent different business concepts, they do not align with the fundamental purpose of organizational charts. For instance, displaying financial data focuses on numerical information, demonstrating relationships between departments involves a different type of chart that highlights cross-functional teamwork rather than hierarchical order, and mapping out a project timeline is specific to project management, which is not the primary aim of an organizational chart.
