Final answer:
Project managers have more authority in a balanced matrix structure than in a weak matrix structure.
Step-by-step explanation:
In a balanced matrix structure, project managers have more authority than in a weak matrix structure. In a balanced matrix structure, there is a balance of power between the project manager and the functional managers, meaning that the project manager has more control over the project and its resources. On the other hand, in a weak matrix structure, the functional managers have more authority, and the project manager's role is more limited.
