A recently released book uses lean principles to illustrate how to improve the value chains of various industries. Improving the Extended Value Stream: Lean for the Entire Supply Chain, (Productivity Press, 2006), by Darren Dolcemascolo, demonstrates the use of lean principles in the extended value stream. In workbook form, the book includes tips on how to magnify the benefits of lean on the production floor by extending the principle throughout the enterprise.

Most companies have used lean to perfect their internal processes, and this has been very beneficial to the bottom line. Dolcemascolo argues that such limited use restricts the benefits that come from lean’s use across the enterprise. He makes a case for the benefits of lean’s extension—increased profitability, reduced lead times and inventory, and better quality. Techniques addressed in the book include extended value stream mapping, process kaizen, outsourcing strategy, supplier evaluation and supplier integration, as they relate to lean supply chains.
