What is the consequence of exceeding an effective span of control for a supervisor?

Exceeding an effective span of control for a supervisor leads to a greater likelihood of task mismanagement. When the number of individuals or tasks under a supervisor's oversight becomes too large, it can overwhelm the supervisor's capacity to manage those tasks effectively. This can result in missed communications, poorly executed tasks, and a general decline in the quality of supervision. As supervisors struggle to maintain adequate oversight, the likelihood of errors and issues in task completion increases, ultimately affecting the overall performance of the team.

In contrast, options that suggest more tasks can be managed effectively, increased efficiency, or better communication within the team overlook the essential limits of supervision. Effective management relies on a balance; beyond a certain point, increased responsibilities hinder rather than enhance operational success.
