When holding a business meeting, the best way to keep the meeting on track is to:

use a checklist.
write an agenda.
prepare ahead of time.
establish a routine.

All of the options mentioned can help in keeping a business meeting on track. However, the most effective way to ensure a focused and productive meeting would be to write an agenda. This document outlines the topics to be discussed, the time allocated for each topic, and who will be responsible for leading the discussion. By setting a clear agenda, participants can stay focused, know what to expect, and avoid going off tangent during the meeting. Additionally, preparing ahead of time, using a checklist, and establishing a routine can also contribute to maintaining the meeting's focus and efficiency.
