Stories and details on the many people contribution to lean manufacturing and modern manufacturing in general.
This week we will have a look at another Japanese word that is often used in lean: hitozukuri. You may already know the similar word, monozukuri, to make things. Hitozukuri applies this to people. No worries, I won’t ask you to give birth, but rather tell you how to grow your people. Read on…
In this blog post I would like to introduce another Japanese term used in industry: Mendomi. Used at Toyota and also other Japanese firms, it means to take care of your employees. And, Toyota makes a good effort on this, albeit not flawlessly. Let’s dive deeper on what mendomi means (but don’t expect to find a new religion in there…).
As mentioned in my last post, continuous improvement (kaizen) is done through people, ideally close to the shop floor. You should always look for people to develop and grow, as they in turn nurture your continuous improvement. While it is really hard to give specific recommendations that apply to everybody, let me muse a bit on the topic.
One core aspect of lean manufacturing is continuous improvement, or kaizen in Japanese. This concept emphasizes ongoing, incremental enhancements to processes, products, and services. Yet, there are commonly differences between how Toyota does kaizen and how the rest of the world does kaizen. These mostly relate to who does most of the kaizen activities. In Western companies, kaizen is usually driven by management. At Toyota, most of the improvement originates from and is handled on the shop floor. Let me explain…
Overburden (muri) is one of the three evils of manufacturing, along with unevenness (mura) and waste (muda). Out of the three, overburden is probably the least understood. Hence, in this post I will look deeper at overburden, including plenty of examples as well as the effects of overburden on your people.
When we are talking about lean manufacturing, we often focus on the tools like kanban, 5S, SMED, and many more. Sometimes, but harder to grasp, is the underlying culture and philosophy of continuous improvement and PDCA. Part of this culture is what you could call the soft power of the Toyota Production System. This is a form of decision making in contrast with the “hard power” more common in Western companies. Let’s have a look:
Managing problems 
is an important part of manufacturing because it allows companies to identify and address issues that can impact product quality, production efficiency, and overall profitability. However, it is not to be confused with actual improvement. While taking care of the problem (hopefully) makes the problem go away, actual kaizen requires that the problem should not come back.
Toyota is (among other things) famous for its team structure on the front line. They have a quite low ratio of team members to supervisors, and I believe that is part of their success. Whereas many Western companies overstuff their hierarchy, at Toyota supervisors actually have the time to help their people and to also improve the operations. Let me dig deeper into that. This blog post was inspired by the new book by Baudin and Netland, Introduction to Manufacturing.
