Complicating the issue is that some senior leaders have an absolute unwillingness to share their vision with their subordinates. This may be the result of the senior's insecurity with their vision or even worse, their own lack of vision (i.e., they have nothing to share). Make your best effort to have good communications with the boss and do the best you can in extracting his strategic vision. Failing this, you're on your own and will have to maintain some level of self-awareness and a sensitivity to your boss's shortcomings.
Just know you are in shoal waters. Someone once said, "when you and your boss have a difference of opinion - your boss owns 'the opinion' and you own 'the difference'."
