The authors who coined the phrase "lean manufacturing" offer new guidance to lean implementers with their breakthrough guide, Seeing the Whole: Mapping the Extended Value Stream.
James Womack and Daniel Jones, who coined the phrase "lean manufacturing" in their book The Machine that Change the World and authors of the best-selling Lean Thinking, offer new guidance to lean implementers with their breakthrough guide, Seeing the Whole: Mapping the Extended Value Stream They explain that "seeing the whole picture" is primarily interested in the removal of overproduction, unnecessary inventories, and unnecessary transportation from the extended value stream

An extended value stream is all of the actions, both value-added and wasteful, required to bring a product from raw materials into the arms of the customer.
Seeing the Whole presents a method to guide groups of managers towards eliminating the waste in the extended value stream.
This method proposes a progression through two Future States to an Ideal State after the Current State is jointly identified and agreed upon.
Future State 1 addresses in-plant product flows.
Future State 2 examines information and transport links between facilities, and the Ideal State begins to resize and relocate activities in order to compress the value stream.
The process of developing an Ideal State can provide an invaluable target for steering each value stream, for every new product generation, towards perfection.
Finally, Womack and Jones show readers how to create a value stream plan for mapping the extended value stream.
Seeing the Whole provides step-by-step guidance for mapping the extended value stream using the example of a windshield wiper that travels 5300 miles over 44.3 days before reaching the customer.
The value-added time of this extended value stream is 54.7 minutes.
Womack and Jones walk the reader through the mapping steps that will eliminate the waste in this process.
As part of the Lean Tool Kit Workbook series published by the Lean Enterprise Institute, Seeing the Whole offers practical how-to information on mapping extended value streams.
Eventually value streams can be compressed and smoothed to a point where a large fraction of the original steps and practically all of the throughput time are eliminated.
The value stream getting there first will have an overwhelming competitive advantage.
Seeing the Whole: Mapping the Extended Value Stream is available from American Technical Publishers and sells for GBP69.00.
