Managers and executives today face a “prisoner’s dilemma” in which they have to “betray” other departments or companies along a shared process in order to optimize their portion of it, according to management expert James P. Womack, founder of the nonprofit Lean Enterprise Institute (LEI).
Womack, who led the MIT research team that coined the term “lean” management, made his comparison during the opening keynote at the Eighth Annual Northeast Shingo Prize Conference, September 25-26, 2012, at the DCU Center, Worcester, MA. Womack’s presentation was titled “Learning to Share Your Value Streams.”
“Value streams or processes flow horizontally across departments, functions, and enterprises,” Womack explained. “But they are organized vertically with incentives for business people to optimize their separate portions of processes, rather than cooperate to increase the value delivered by the whole process, which is what customers care about.”
Thus, business people face a prisoner’s dilemma in which everyone could gain valuable benefits by cooperating, but find it difficult to coordinate activities in order to collaborate.
The prisoner’s dilemma scenario grew out of game theory research. Two suspects are arrested by police, who, lacking enough evidence for conviction, separate both prisoners, then offer each the same deal: If one testifies against the other and the other remains silent, the betrayer goes free and the silent prisoner receives the full 10-year sentence. If both prisoners remain silent, each gets only six months in jail on a minor charge. If each betrays the other, each gets a five-year sentence.
“It’s an accurate behavioral metaphor for businesses sharing a process in which a win-win possibility becomes a lose-lose actuality — which happens every day in the real world – because managers and executives don’t have a way to share an analysis of their common processes,” Womack said.
The solution is for every company or department touching a value stream to “get out of their cells” by drawing a value-stream map together showing the opportunities for creating more value with less resources and waste.
“Sharing is not natural,” Womack said. “But it is necessary to escape the prisoner’s dilemmas we all face every day.”
Womack, who now is a senior advisor to LEI, is the co-author with Daniel Jones of such influential business management books as: The Machine That Changed the World (with Daniel Roos; Macmillan/Rawson Associates, 1990), Lean Thinking (Simon & Schuster, 1996, 2003), Seeing The Whole: mapping the extended value stream (Lean Enterprise Institute, 2002) and, Lean Solutions (Simon & Schuster, 2005).
His most recent book, Gemba Walks (Lean Enterprise Institute, 2011), is a collection of his essays on lean management, based on 10 years of walking value streams at a variety of companies.
What is Lean?
The terms lean manufacturing, lean production, or lean management refer to a complete business system for organizing and managing product development, operations, suppliers, customer relations, and the overall enterprise. It requires less capital, material, space, time, or human effort to produce products and services with fewer defects to precise customer desires, compared with traditional modern management.
Toyota pioneered lean management as a complete business system after World War II. During the late 1980s, a research team headed by Womack at MIT’s International Motor Vehicle Program coined the term “lean” to describe Toyota’s system.
