Sometimes those in power can be unyielding in their vision, which can be a problem if you are convinced their vision is all wrong. In an article for Harvard Business Review, Priscilla Claman addresses six ways to shift their gaze.

Share your perspective with colleagues to gather their feedback and confirm that your reasoning is sound. Then formalize that argument into a brief presentation supported with facts and graphs. Find an expert that senior managers would find credible to go over your findings and validate them.
