why is a functional organization structure beneficial?

Question

Functional Organization: A hierarchical organization where each employee has one clear superior, staff are grouped by areas of specialization, and managed by a person with expertise in that area.

Answer 1

Because when a bunch of people work together, they need to know what are their responsibilities and outputs are. The larger the group of employees in a company, the more they need an organization. The military is a clear example or hierarchy and sticks to it quite rigidly.
