What If Your Customer Takt and Your System Takt Do Not Match—Small Fluctuations

Christoph Roser January 6, 2026

One of the key parameters for setting up and running any production system is the customer takt (i.e., the customer demand). This is measured as the average time between the demand of a customer for one product, based on the available working time. In the grand picture, the customer takt (the customer demand) should match the line takt (the production speed of the line). But what should you do if it doesn’t? Let’s investigate this in a small series of posts. This first post looks at small fluctuations.

Work standards are key to kaizen, and their correct use requires process confirmation. The BMW Group Dingolfing plant does an outstanding job with this process confirmation, driving their continuous improvement. This gives BMW automotive plants an outstanding performance on par with Toyota. In this last post on the series on the process confirmation standards at BMW Dingolfing, we dig deeper into the confirmation for the work standard documents and the digital displays used to manage the product variety coming down the line.

Process confirmation is essential for maintaining standards, which are essential for continuous improvement. In my previous posts I introduced the process confirmation standard at the BMW Group Dingolfing plant, which helps BMW to achieve efficiency on par with Toyota. We already looked at the verification of the material supply standards and 5S. In this post I will talk more about the Gemba standards for the actual work. They demand improvement ideas directly from the shop floor, which is the best way to have fast kaizen cycles toward operational excellence. Read on!

Continuous improvement in lean works through work standards. Improving the standards improves your processes. However, all of this is for naught if the standard is not followed. In this series of blog posts I will look in more detail at how the BMW Group Dingolfing plant (a company on par with Toyota in terms of efficiency) does process confirmation on the shop floor. And, maybe even more important, how they drive the whole improvement process through the front-line workers on the shop floor using this process confirmation.

A Visit to the Fendt Cabin Plant in Asbach-Bäumenheim—Part 3

Christoph Roser December 2, 2025

In this third and last post on the Fendt Cabin Plant in Asbach-Bäumenheim, I will look in great detail at their digital dashboards as well as their excellent blue collar–driven continuous improvement process. I believe that true excellence can be achieved only through fast front-line improvement driven by the operators, and Fendt in Asbach-Bäumenheim is a good example of where it worked. As shown in my previous post, this plant has an outstanding performance, and the improvement system is the key driver for that. Read on!
