Well, what we do know is that a plan is based on predicates. For x to occur, y must also occur. The trouble is that in the future, certain things just cannot happen; that is when we need to become agile. We must adjust our planning to correlate with our current surroundings - essentially you cannot force things that just won't happen and if you do the result is an unrealistic forecast. With that being said, you must know where you want to go - but we cannot define how we are going to get there. Because in the end, it`s not particularly important how we got there, just that we get there. "Drive to arrive"
