Answer:
Functional Principles
Step-by-step explanation:
When it comes to proper organization in businesses, there are several principles that should be adhered to in order to achieve proper functioning. The functional principle indicates that the roles of every person in a department, be it managers or subordinates, must be properly explained to them in order to achieve smooth operations in the business.
When roles and responsibilities are properly explained, each person becomes aware of the expectations from him at every point in time. This in turn allows for efficiency in the discharge of duties. So, when Dean explains that the role of the manager should be properly explained, he is making reference to the functional principle.
