Span of Control

On page 51 of the textbook, there is a discussion of "Span of Control", which refers to the number of people that can be supervised by one manager without causing the manager to become over-worked or over-stressed. The upper limit to the Span of Control is estimated to be 7-9 persons.

I think that this number is actually an underestimate, and that improvements in information technology have probably increased the Span of Control to about 20. When I was in graduate school, there were some professors who supervised over 20 graduate students primarily by communicating with them through email, and saw their students in person only when it was absolutely necessary. This helped the students to utilize the professor's time in a more effective manner, and it was not difficult for the professor to maintain good communication with 20 students on a routine basis.

I think that you are partially correct. The book says that “the upper limit of effective span of control is 7-9 persons.” I place the emphasis on effective because it is possible to have more individuals in a span of control, however, the issue is how effective is the manager?

I was just recently talking with an engineer at BAS and he said that he was on a 20-25 person team with one “team leader.” He was very frustrated because this team leader was not doing a good job of communicating to him what needed to be done. There were several tasks that needed to be done, each task requiring communication and guidance. Because of this high span of control, the team was suffering. The issue was not the team leader’s management abilities, but he had too many people to manage. My point is that business is much different than graduate class.

I believe that communication must go beyond e-mails and must include face-to-face communication in order to be effective which requires more time spent per individual.
