Brilliant Stuff! Comprehension indeed should drive action! Lack of subject comprehension has pretty much being the bane of Nigeria, politically and in business. I would split comprehension into two: comprehension of problem, and comprehension of solution. Comprehension of problem would include: ‘what’ (what challenge are we facing), ‘why’ (why are we facing this challenge); while comprehension of solution would cover the ‘how’ (how do we overcome this challenge and get our desired result) and then the ‘when’ (when is the best time to implement the how).
