The 2005 book by james-p-womack and daniel-t-jones that extended the lean framework from production to consumption. Where lean-thinking focused on how companies eliminate waste in their internal value streams, this book examines how companies and customers together can resolve the waste embedded in the consumption experience itself.
The lean consumption concept
The book introduces lean-consumption as the companion to lean production. The core argument is that consumption is itself a process, and that consumers expend enormous time, effort, and frustration in acquiring, using, maintaining, and repairing products and services — waste that conventional lean thinking, focused on the producer's value stream, ignores entirely. The book proposes six lean consumption principles:
These parallel the producer-side five principles from lean-thinking but reframe the analysis from the customer's perspective.
What TPS concepts are being translated
The lean consumption framework extends TPS logic beyond its original scope. TPS was designed to optimize production; the consumption-side analysis is Womack and Jones's own extension rather than a direct translation of Toyota practice. The book draws on the pull-principle (making value available where and when the customer needs it) and the value-principle (defining value from the customer's perspective), but applies them to service design, retail, and post-sale interaction rather than to production scheduling.
Target audience
The book is aimed at managers in service industries as well as manufacturing companies with significant post-sale service obligations. It was published at a time when lean was expanding rapidly into healthcare, banking, and retail — sectors where the customer's consumption experience is the primary value-creation site.
Reception
The book received a more mixed reception than machine-that-changed-the-world or lean-thinking. The lean consumption concept was seen by some practitioners as an abstraction too far from TPS operational detail. It did not win the Shingo Prize (unlike those earlier works). However, the lean consumption framing influenced lean service design practice and anticipated later customer-journey and design-thinking frameworks.
Companion article
The book's core arguments were previewed in the Harvard Business Review article lean-consumption-article (March 2005), published the same year.
