A matrix organizational structure is characterized by employees being responsible to two managers, a functional manager and a project manager.
Step-by-step explanation:
A matrix organizational structure is characterized by employees being responsible to two managers. This means that individuals in a matrix structure report to both a functional manager (based on their expertise or skills) and a project manager (based on the project they are working on). This allows for more flexibility and the ability to draw upon diverse skills and resources from different areas of the organization.
