Lack of materials or goods to satisfy customer orders under current market conditions represents an extremely costly and important problem facing businesses today. This is a problem that companies have spent hundreds of millions of dollars trying to solve. This book introduces a new theory, 3C, which will solve these problems. The authors, experts from Lucent Technologies, discuss in detail the relationship between the 3Cs - capacity, commonality, and consumption - and how this relationship can revolutionize your business. You will learn how to: reduce overhead expense and improve shipping performance by using the business capacity as the basis for materials planning; reduce investments in inventory by using the commonality of components; obtain dramatic improvements in the lead time of customer orders by using the actual consumption of materials instead of inaccurate sales forecasts as the basis for purchasing. The new and exciting techniques based on 3C generate immediate business benefits, for example: executing the purchasing function with a new criteria and formulae that can eliminate material shortages and significantly improve shipping performance, sales volumes, operating expense and company image. 3C-A Proven Alternative to MRPII for Optimizing Supply Chain Performance gives you the knowledge and practical guidelines to better manage end-to-end Supply Chains and eliminate the expensive and annoying problem of material shortages that most businesses suffer.
