The 80/20 CEO: Take Command of Your Business in 100 Days introduces the Profitable Growth Operating System (PGOS), featuring 80/20. PGOS is based on the five management practices 80/20, strategy, talent, M&A, and lean. It is for all senior-level executives, established, rising, or aspiring, who want to lead their organization in strategic growth. PGOS was born in the intensely growth-focused environment of middle-market companies held by private equity, but it applies to virtually any business intent on improving and growing. The middle market is a powerhouse for the U.S. economy. Yet many of these companies are little known to the general public. PGOS will help them break through with a proven process to double the company's sales in three to five years.
