Great strategy, not executed, can't possibly have any effect on performance because it doesn't actually affect anything. It's like planning for a successful surgery to remove a tumor. If no one picks up the knife and actually operates effectively, the diseases will persist.
Part of strategy is figuring out what you're good at, figuring out what you're not good at, and then getting yourself in position to succeed by doing mostly what you have a competitive advantage doing.
In any branding strategy, you need to figure out what is the image you want to project. Then behave accordingly. And above all, cultivate the media and those who will help you burnish your reputation.
