The document discusses different types of organizational structures including simple, functional, divisional, matrix, network, team-based, and project-based structures. A simple structure has one person in control with little formal processes. A functional structure groups activities like finance and production departmentally. Divisional structures separate by products, services, or geography. Matrix structures combine functional and divisional reporting. Network structures connect groups through projects. Team and project-based structures organize people into cross-functional teams focused on specific tasks. Each structure has advantages like specialization but also disadvantages like narrow perspectives or power struggles between departments.
