The document discusses different types of organizational structures: simple, boundary, matrix, boundaryless, and team-based. A simple structure has low departmentalization, wide spans of control, and centralized authority. Boundary structures include functional, which groups similar occupations, and divisional, with semi-autonomous units. A matrix structure assigns specialists to projects. A boundaryless structure is not defined by predefined boundaries. Team-based structures use small, rule-oriented teams where members act as managers.
