The "chain of command" is a system that outlines the hierarchy of authority within an organization. It defines who reports to whom, ensuring that decisions and instructions flow smoothly from the top levels of management down to the employees. This structure helps maintain order and clarity in roles and responsibilities. In a typical business, for example, the CEO is at the top of the chain, followed by managers and then employees. Each level has specific duties and communicates with the level directly below it, facilitating effective management and coordination throughout the organization.
