Presents an expanded concept of creating flow in real life environments by providing knowledge on how to create flow through shared resources, or monument and/or high capital equipment that produces parts for multiple product families in order to support mixed model production

  • Provides additional insights on existing mixed model concepts, such as determining product family, takt capability, and heijunka, or load level scheduling
  • Describes sequenced FIFO lanes, offset scheduling, calculating interval for shared resources, and linking shared resources with the pacemaker
  • Examines establishing guaranteed turnaround times for shared resources so the time it takes for a part to cycle through the process is fixed and consistent
  • Includes a CD with spreadsheets, samples, and case studies


Following in the footsteps of its bestselling predecessor, Kevin J. Duggan, an executive mentor and recognized authority on Lean and Operational Excellence, draws on more than 10 years of experience and learning to provide Creating Mixed Model Value Streams, Second Edition. This second edition takes a step-by-step approach to implementing Lean in complex environments and describes which Lean techniques to use when faced with difficult situations—including high product mix, scheduling problems, shared resources, and unstable customer demand. In addition to a new section on handling shared resources to support mixed model production, the second edition:

  • Contains updates to sections on mixed model value streams
  • Introduces new information on constructing product family matrices
  • Expands on the concept of takt in mixed models
  • Provides additional insights on existing mixed model concepts, such as determining product family, takt capability, and heijunka (load level scheduling)
  • Presents new concepts on sequencing work, such as offset scheduling and sequenced first-in, first-out (FIFO) lanes

Illustrated with a case study based on actual experience as well as a CD with helpful tools, the book walks readers through the reasoning the author has used with great success in practice. It delves beyond the basics of value stream mapping to explain how to create future states in a manufacturing environment characterized by multiple products, varying cycle times, and changing demand. Demonstrating advanced techniques for creating flow through shared resources, it also considers the concept of a guaranteed turnaround time for the shared resource.

The Accompanying CD Includes:

  • Spreadsheet and tutorial for sorting products into families
  • Spreadsheets for calculating equipment required and for determining the interval for Every Part Every Interval (EPEI)
  • Samples of visual method sheets for standard work
  • Case study value stream maps and mapping icons
  • product dimensions: 1/2 x 11 x 8.5 inches
  • CD included

Editorial Reviews

... required reading for most firms that are serious about Lean transformation. It not only addresses a critical need for companies in a high-variety product environment, but also covers many details in developing your Lean system. It deals with more complex issues, but it is written clearly and presented in a very digestible form. It is one more step toward moving beyond copying what we see in Toyota plants and developing our own Lean production systems.

—Jeffrey K. Liker, University of Michigan and Shingo Prize-Winning Author of The Toyota Way

Praise for the Bestselling First Edition:

Finally, a book that addresses the real world complexity of implementing lean in a mixed model environment! Creating Mixed Model Value Streams is must reading for anyone who is trying to make improvements beyond a basic value stream map. From selecting a product family to scheduling and dealing with customer demand, this book shows you how to implement a lean value stream in a way that everyone will understand.

—Glynn Miller, Director, Consumer Centered Enterprise

This excellent how-to guide will help set free those of us who have been handcuffed by complexity in our manufacturing systems. It translates theoretical lean into practical guidance for use in the trenches.

—Al Mason, Manager, Process Improvement, Goodrich Corporation

We work with companies across all industry sectors enabling them to keep increasing their levels of Lean expertise. One of the issues we see them struggle with time and again is, 'How do we make product flow when there are a variety of products in the same value stream?' Without any quality books on the topic, it has been no easy task to explain - until now. This book demystifies and simplifies the concept of Flow in complex environments. When you put the book down, you will understand there is a solution to your situation. Your only regret will be - why didn't I have this knowledge sooner.
