Get the questions right, not the debate long
There are two ways to approach decisions: by questions or debate. By questions, we move forward together one question at a time. Questions are anything unknown, unverified, unclarified, undecided or unresolved. The velocity of question based decisions is dramatically faster and more realistic than decision by debate.
Don't postpone action for perfection
However much confidence and consensus a decision holds, it creates as much uncertainty as we would have if we postpone it. We can make good decisions well that result in all kinds of uncertainty. A sense of certainty is not a guarantee of a good decision. In most cases action is necessary to move things forward in a positive way.
Keep a nimble tempo
We can make decisions faster simply by timing conversations for increased frequency. A decision based on daily or bi-weekly conversations will go faster than those with weekly or monthly conversations. A faster tempo does not add more total effort time to a decision. If anything, a slower tempo results in the inefficiencies of more effort time.
