The devil is in the details. That is my only point here. What can be missed is the fact this devil is particularly devilish. Every situation, set of circumstances, problem, or issue has its broad-brush look and feel. From that perspective, it takes on its special definition. Given that definition, a proactive leader can draw on his insight and experience and take appropriate action. He does not need the details to know what to do. In fact, he is so oriented to managing people and processes at this level he quickly becomes impatient with those who insist on providing far more detail than he wants or needs.
Less successful leaders take a different approach. They want and need every detail, no matter how trivial. They believe the more information they have, the better will be their choices and decisions. These leaders see themselves as thoughtful and thorough. Proactive leaders are, they think, impulsive and inclined to shoot from the hip.
Here is the underlying problem. No matter how much detailed information leaders have, there is most always more information that could be made available, if they are patient enough. There are also things they cannot know and details that will not be forthcoming no matter how patient they are. It is normally possible to know more and impossible to know everything.
