In terms of management, what is considered an effective number of personnel under one supervisor?

The range of 3 to 7 personnel under one supervisor is considered effective because it allows for a balance between the supervisor's ability to manage the team effectively and the team's capacity to function with a level of autonomy. This range promotes open communication, ensures that the supervisor can provide adequate attention to each team member, and maintains accountability within the group.

Having too few individuals, such as in the range of 1 to 2, may lead to a lack of team dynamics and support, as the supervisor may not be able to facilitate collaboration and skill sharing effectively. On the other hand, having too many individuals, like in the range of 8 or more, can overwhelm a supervisor, leading to decreased oversight, potential miscommunication, and difficulty in providing individualized support. The 3 to 7 range strikes a balance that enhances productivity and fosters a positive team environment, making it the most effective choice in a management context.
