This document provides guidance for business leaders seeking to align their company's purpose and strategy. It discusses defining an authentic purpose statement that reflects the original intentions for starting the business. A purpose is not a goal or marketing tagline, but rather the core reason the business exists. Ten principles are outlined for finding and expressing purpose, such as ensuring it is memorable, does not change, and reflects the company's focus. Case studies of independent consultancy Independents United and UNESCO are presented. The document concludes with a checklist to help evaluate if a defined purpose statement is authentic and guiding.
