Yield only to positions that have objective or logically sound foundations or merits. Avoid conflict-reducing techniques such as majority vote, averaging, coin toss or bargaining. When dissenting members finally agree, do not feel that they have to be rewarded or accommodated by having their own way on some later point. Differences of opinion are natural and expected. Seek them out, value them, and try to involve everyone in the decision process.
Disagreements can improve the group's decision.
With a wider range of information and opinions, there is a greater chance of that the group will hit upon a more feasible or satisfactory solution.
