In my most recent academic past I have had the pleasure of working with uni- versities including the University of San Diego in its Supply Chain Management Institute, Brigham Young University, California State University, Chico, and many international universities. Professionally, I have had the pleasure of work- ing with organizations such as MainStream Management as a Lean consultant, American Management Systems (AMS) as a senior principal in their Corporate Technology Group where I was the business practice leader on Supply Chain Management/ERP/EAM/DRP/Lean Principles in an eCommerce environment, and Precision Printers as executive director of Quality, Engineering, R&D, Cus- tomer Service, Production Scheduling and Planning, and Facilities Management. Other organizations that I have worked for include Hill Air Force Base, the Cali- fornia Department of Child Support Services (DCSS), Texas Attorney General’s Office, Child Support Division where I was director of Change Management and Communications, Kraft Foods, and many more. As you can imagine, it is challenging to “lean” out an office full of lawyers or accountants. But in some cases the results were a tripling of throughput using the same number of employees. I have lived and worked in factories in Latin America, Asia, and Europe, I have co-authored articles and books, and I have worked with academic and professionals from as far away as Europe, Japan, and Australia. My broad exposure to a variety of manufacturing and service facilities all over the world has given me the background I needed to write this book. I also need to recognize my family, my wife, Renee Sangray Plenert, and my children, Heidi Lynette Plenert, Dawn Janelle Plenert, Gregory Johannes Plenert, Gerick Johannes Plenert, Joshua Johannes Plenert, Natasha Ida Plenert, Zackary Johannes Plenert, and Chelsey Jean Plenert, who gave me the time I needed to make this book work. Gerhard Plenert xi This page intentionally left blank Preface There are two concepts in management that have become somewhat disasso- ciated but that need to be integrated closely together. The first concept is Supply Chain Management (SCM). Integrating the linkages of the supply chain is an extremely complex task, especially if you are trying to integrate these linkages internationally. Supply chains can be as simple as going to a farmer to buy strawberries or as complex as involving thousands of suppliers, manufacturers, shippers, and retailers. But the failure of any one of the steps in this chain results in the failure of the entire supply chain. Customers do not care about why a product was late or why it was wrong; they only care that it was wrong, and they expected it to be correct. Supply Chain Management (SCM) integrates networks of international com- panies into a structure that allows them to optimize performance as a collective unit. The integration starts with the vendor’s vendor and ends with the cus- tomer’s customer. Three key measures identify the successful performance of the international supply chain: • Cycle time performance • Operating cost minimization • On-time performance and customer satisfaction Information exchange within the supply chain is critical for its successful oper- ation. This requires an openness and trust among all the entities of the supply chain. It also requires a mechanism for the efficient transfer of this information. Traditional methods of information transfer, such as fax, phone, or even e-mail, are too slow. Internet, intranet, and extranet information accessibility allowing all entities in the supply chain to monitor the performance of every other entity is critical to international competitive success. The second concept that needs to be reassessed and that needs to be integrated in conjunction with SCM is Lean. Lean is a tool that facilitates the elimination of waste. And waste can be identified in a multitude of resource areas. Any, and probably all, of the resource areas identified as part of the supply chain contain waste. Lean is the methodology that identifies the waste and then utilizes a bag of tools to attempt to eliminate this waste. The more waste that is eliminated, the greater the value-added time, resulting in greater throughput, lower costs, xiii xiv Preface increased capacity, and reduced cycle times. In the end, utilizing Lean princi- ples provides a supply chain that is more efficient and more responsive to the customer, and therefore more competitive. If every organization in the world worked in exactly the same way, this book would have been very easy to write. Unfortunately, however, no two organizations work alike. Even when the organizations are producing the same output and are right next to each other, they often operate differently because of management style and methods, or corporate influences.
