The problem I think is you have to get them all right. On another thread I mentioned the word alignment. The Political Objective has to be achievable and has to link or align with Strategy and Doctrine and Operations and finally Tactics. That is what makes it all so hard and when something goes wrong there is a tendency to blame one part instead of looking at the whole linkage of different processes. If you fail at the highest level it can affect the outcome of everything else at the lower levels no matter how good each piece is by itself.
