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.
Kaizen
Who Does Kaizen?
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…
Keep Calm and Stop the Line—Part 2
In manufacturing, a common sentiment is that the line (or generally the process) must run. There is some truth to that, but—counterintuitively—for a system to run well you need to know when to stop it too. This is my second post in a series giving you an overview on when it may be better to stop the line rather than keeping it running (and making everything worse). Keep on reading!
Different Ways to Do Kaizen
Kaizen (改善), or continuous improvement, is a cornerstone of lean manufacturing. If you stop becoming better, you will fall behind. But not all improvement activities are equal. There are different ways to do kaizen projects suitable for different situations. Let me give you an overview:
Making the Problem go Away Is NOT Improvement
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’s Master Craftsmen: Takumi
You may have heard of Takumi at Toyota. Takumi in general are highly skilled artisans that excel in their craft. Despite Toyota mass-producing cars using lots of machines, they also employ hundreds of Takumi. This blog post takes a deeper look at what a Takumi is, and why they are so important for Toyota and other Japanese companies.
Where to Start Your Kaizen?
To become lean, you need to improve your factory. Continuous improvement (kaizen) consists of many smaller and/or larger improvements. However, often the first challenge is where to start this improvement. Let me dig deeper into the possibilities and challenges of picking improvement projects, with a particular focus on systems that have multiple independent production lines, which makes everything trickier.
What Is Kaizen?
If you are in lean, you surely have heard of kaizen, and its English translation, continuous improvement process (CIP). It is one of the fundamental parts of lean. Kaizen generally means to improve, and in lean in particular, it means to continue improving forever. Pretty much all companies that haven’t gone bankrupt do this, often without using the word kaizen. You need to continuously improve in order to survive the harsh realities of competition.
