Which method of communication allows for a larger span of control, according to management principles?

The method of communication that allows for a larger span of control is written instructions. This is because written communication can be distributed to multiple individuals simultaneously, ensuring that everyone receives the same message and information without the need for direct interaction. It enables managers to manage a larger number of employees effectively, as they can provide clear guidelines and expectations that can be referenced by employees at any time.

Written instructions can also be evaluated, revised, and standardized, making it easier for a manager to ensure uniformity across a team or organization. This adaptability and clarity promote efficiency and reduce the likelihood of miscommunication that can arise from more interactive communication methods.

In contrast, one-on-one meetings, verbal briefings, and group discussions typically involve more direct interaction and personal attention, often leading to narrower spans of control. These methods engage individuals or smaller groups, which may provide depth and nuance but limit how many people can be simultaneously managed or communicated with at one time.
