In running effective meetings it is helpful to:

A) encourage the clash of personalities,not ideas.
B) avoid using time frames,allow for free flow.
C) establish ground rules for debate.
D) attend to divergent issues even if it is time-consuming.

Establishing ground rules for debate can help to maintain order and ensure that everyone has a chance to express their ideas without conflict or disruption. Encouraging clash of personalities (A) can lead to unproductive arguments and personal attacks. Avoiding time frames (B) can lead to meetings that run too long and lose focus. Attending to divergent issues (D) is important, but it should be done within the structure of the meeting and should not take up too much time.
