The most usual type of organizational structure is a hierarchical org chart. The chain of command runs from the top (e.g., the CEO or manager) down (e.g., entry-level and low-level employees), and each employee has a supervisor. Its purpose is to depict the organization's reporting relationships and chains of command. Employee names, titles, and job titles are typically displayed in boxes or circles, with lines connecting them to other employees and departments. By seeing at the company organizational chart, people can quickly understand how the organization is designed, the number of levels, and where each employee fits into the organization.
