A gap analysis is a fundamental model.
Where do we want to go? What is the goal? What does success look like?
Where are we now?
So goes the gap. Bordered by where we are now and where we want to be in the future is the gap. In that gap are all the problems that have to be solved and all the decisions that have to be made. All learning, from small lessons to large, is based on the gap.
Standing on the shore, looking over the ocean, far out, a shape leaps out of the water. On closer inspection, you discover, it is a porpoise.
You see, out of the gap, you may achieve your objective and find it empty. You may reach your goal and find it unworthy. Before you set your goal, you must look out to the ocean and find your porpoise.
