The leader knows “what” before he knows “how,” but he knows “how” before he knows “when.” It is the “when” element which makes fools out of wise men. We often know what will happen, but we seldom know when (precisely when). If we are not careful, our careless assignment of timelines may undermine our team’s trust. The leader needs to separate the “what” from the “when,” or else the latter will jeopardize the credibility of the former.
