The Art of the Question | Robert W. “Doc” Hall | Compression Institute

“Twenty-five years ago, I tried to coach adult college students to seek and solve problems using the classic Deming PDCA Circle. In classrooms, students were unused to identifying their own problems rather than having them pre-defined. The first time through this exercise, over half did not reflect on a problem to seek root cause. Instead, they went shopping for a gizmo, a program, or a recipe to fix the problem – a quick-fix mentality.”

Michel Baudin‘s comments: 33 years ago, Robert W. Hall wrote Zero Inventories, the first original, technically meaty book in English about Lean Manufacturing, and I have had great respect for him ever since.

“…Nakagawa, who has been a TPS practitioner for four decades, doesn’t believe in seeing things on his computer screen -he prefers to go where the action is. “Can a computer smell? Genchi Genbutsu is very important because only on-site will your sensory organs be alert – smell, sound, vision,” he says….”

Michel Baudin‘s insight:

Perhaps, Mr, Nakagawa has not heard of Google Nose, the app announced on April 1.

In all summaries,TPS has two pillars, but never the same. In this article, the pillars are “respect for people” and “continuous improvement.” To Ohno, they were Just-in-time (JIT) and Jidoka, with JIT covering production control, logistics, and supply chain management, while Jidoka was a complete approach to the engineering of production lines where humans interact with machines.

You could try to implement Ohno’s JIT and Jidoka without respect for people or continuous improvement, but it would not work well. Conversely, if all you focus on is respect for people and continuous improvement, you won’t get TPS either. You need both, and, perhaps, two pillars are not enough.

Broadly speaking, the two pillars in this article are about management; Ohno’s pillars, about technology. As TPS is based on the interplay of management and technology, perhaps these are its real “two pillars.”
