Which of the following is one of the steps to take when preparing for a meeting to help improve meeting productivity?

A) Encourage participation
B) Put the results to effective use
C) Distribute meeting minutes to participants and other interested parties
D) Make sure the meeting is necessary
E) Lead effectively and participate fully

Ensuring the meeting is necessary is an important step in improving meeting productivity because unnecessary meetings can waste time and resources. Encouraging participation, putting results to effective use, distributing meeting minutes, leading effectively, and participating fully are also important steps, but they may not necessarily improve meeting productivity if the meeting itself could have been avoided in the first place.
