A look at the world's most profitable supply chains reveals that they revolve around process-based relationships that integrate suppliers throughout the product's lifecycle. That is the basis of the report Best Practices in Supply Chain Partnership and Certification, available from Best Practices LLC of Chapel Hill, N.C. The benchmarking report states that managers who overlook the partnership aspect of a supply-chain relationship consistently yield lower profit margins due to higher processing errors and supply costs. Also reviewed are how top companies have improved supplier certification and partnership to cut lead times and inventory by more than 50% and boast 100% elimination of processing errors and paperwork. Insights from 150 companies, including Federal Express, IBM Corp., and Proctor & Gamble are included.
