"The Fourth Moon" is another book about closing the gap between implementation and strategy. It argues that business owners have no problem planning for success. They have a problem acting on that success. Part of that problem, according to "The Fourth Moon" is the reliance on one-time fixed documents, like annual performance reviews, yearly (or longer) business plans, and balance sheets. While helpful for providing a snapshot, these documents often gather dust during the course of real life. A better approach is to use these planning and measuring documents as a starting point to chart your course and then rely on regular check-ins to guide your way.
