Answer:
Wide span of management.
Explanation:
Wide span of management involves a single manager overseeing a large number of employees, and this gives rise to a flat structure. A manager's span of control is the number of subordinates he supervises.
This form of management is ideal if employees are very competent, there is well defined standard operating procedure, and there is low expectation for problems.
In this situation there is no need for many managers as the employees to a large extent manage themselves effectively to meet set goals.
