You cannot plan a strategy without a Vision of where you want to be in the future and your vision will never be realized without a Strategy!

The two go hand-in-hand.  Indeed, we are not able to predict the future.  However, with careful, insightful, visioning, you can certainly determine where you want your organization to be in the future.  With that ideal in mind, you can establish the path to your goal …continually making course corrections as unforeseen obstacles (and opportunities) occur.
