In simplest terms, strategy is the means by which we travel from a current state to a future desired state. The realization of strategy is, by necessity, a learning journey.
Strategy presupposes that there are things we know, but also that there is a great deal we do not know. It gives us a framework for making decisions as we encounter new information, as we learn.
As a result of learning we should, of course, adjust strategy.
And so the process continues.
