Management structures refer to the way an organization arranges its hierarchy and roles to achieve its goals. These structures define how tasks are divided, coordinated, and supervised. Common types include hierarchical, flat, and matrix structures, each with its own advantages and challenges. In a hierarchical structure, there are clear levels of authority, with each employee reporting to a supervisor. A flat structure reduces the number of management levels, promoting a more collaborative environment. The matrix structure combines elements of both, allowing for flexibility and improved communication across different departments, such as marketing and sales.
