Strategy is getting it right and doing it right. On the one hand, we have to pick the right course of action. On the other hand, once chosen, we have to carry it out properly.
If our strategy and its execution are both flawed, the effort is "doomed from the beginning." Our chances of success are zero, nil, nada, zilch.
If our strategy is sound but its execution is flawed, we are guilty of muffing it. We have what is commonly known as "a botched job."
An odd situation arises when our strategy is flawed but we execute it flawlessly. In this case, we are doing extremely well something we shouldn’t be doing at all.
Only when our strategy and its execution are sound do we stand a pretty good chance of success. Even then success is not guaranteed.
