An advantage of a functional organization structure is that workers are divided by specific professions, For example, advertising professionals work together in the same department, as do finance employees. Work can be easily coordinated in a functional organizational structure. The advantage of a product organizational structure is that all efforts emphasize ensuring product quality. For example, a vice president of women's clothing in a department store can focus all efforts on building sales for one product line. Matrix structures combine the benefits of both functional and product organizational structures, especially for short-term or ad hoc projects.
