The PDCA (Plan-Do-Check-Act) is one of the best-known lean methods, and one of the key philosophies for continuous improvement. However, despite its apparent simplicity, there are many struggles involved with its proper use. It seems that especially the Act part is challenging. Hence, let me dig deeper into why and how to Act in the PDCA.
Lean Philosophy
On Facts vs. Opinions
In lean, as well as in many other areas, facts hold much more value than opinions. But what are facts, and what are opinions? Unfortunately, this is not black and white, but a big gray area. This blog post is based on a question by a reader on my earlier post “Why It Is So Important for Managers to Listen!” Let’s dive deeper into how to distinguish facts from fiction, and how to get facts in the first place…

As I started to write this article, I saw this type of waste as not so helpful in lean manufacturing. Colleen Soppelsa, whose opinion I respect very much, on the other hand, sees it as a very helpful type of waste. Time to sort out my thoughts and reconsider the pros and cons of including “unused human creativity” in the lineup of the types of waste. Maybe by the end of this article I will change my mind. Let’s see…
Dark Lean
During the European Lean Educator Conference in Chemnitz, I had the opportunity to listen to a presentation by Nadja Böhlmann on “Dark Lean.” In order to do good lean, we need to understand why some lean projects are bad. Or, in order for practitioners to reach the light side of lean, they need to understand more about “Dark Lean.” Let’s have a look at the darkness to understand the light…
A Common Mistake in Doing Lean: Skipping the Details!
Lean manufacturing is a great set of philosophies and tools to improve your production system, or for that matter any kind of operational system. Yet, many supposed lean implementations fail. One of the various reasons for failure of a lean project is a lack of attention to detail. Let me explain:
