We worked with Computer Sciences Corporation (a $10 billion consulting and systems integration firm) and the University of Tennessee to develop and write the book Keeping Score: Measuring the Business Value of Logistics in the Supply Chain. The book was published by the preeminent professional association for logistics executives, the Council of Logistics Management (CLM), which has published about two dozen books since its founding in 1963. In less than two years, Keeping Score has become one of the best–selling books in the history of CLM, which has 15,000 members worldwide. Written for senior executives in and outside of the logistics function, the book explored the growing importance of measuring supply chain performance. It also explained practical steps that top- and mid-level managers can take to dramatically improve customer service and inventory management, reduce supply chain costs, and enhance shareholder value.
