Final answer:
The matrix structure is often used for temporary projects as it incorporates cross-functional teams which are ideal for project-based tasks, unlike more permanent and stable bureaucratic structures with explicit rules and hierarchy.
Step-by-step explanation:
The type of organizational structure that is often used for temporary projects is the matrix structure. A matrix structure facilitates the use of cross-functional teams which include members from various departments working together temporarily on project tasks. This differs from other organizational structures like the functional structure, which is organized by departments; the divisional structure, organized around products, services, or markets; and the hierarchical structure, which is a traditional top-down approach.
The question focuses on bureaucracy characteristics which can give insight into why a matrix structure is ideal for temporary projects. In bureaucracies, there is often a hierarchy of authority, explicit rules, and a division of labor, but there's no coercion to join, as bureaucracies are generally stable, permanent organizations, unlike the temporary teams found in matrix structures.
