The Five Messages Leaders Must Manage (Unabridged‪)‬

If you want to know why so many organizations sink into chaos, look no further than their leaders' mouths. Over and over, leaders present grand, overarching - yet fuzzy - notions of where they think the company is going. They assume everyone shares their definitions of "vision," "accountability," and "results." The result is often sloppy behavior and misalignment that can cost a company dearly. Effective communication is a leader's most critical tool for doing the essential job of leadership.
