The BMW Finger Line Layout

As part of my grand tour of German automotive, I visited the BMW plant in Leipzig. As of now, this is my second most favorite German automotive plant, after BMW in Munich. I will talk more about this quite well-organized and indeed beautiful plant in a later post series, but in this post I’m going to explain their very interesting and novel way to set up their assembly line. They call this the finger structure or comb structure (Fingerstruktur or Kammstruktur) because the line layout looks like the fingers of a hand or the teeth of a comb. I found this approach quite unique, and hence would like to share it with you.

Variable Takt at Fendt in Marktoberdorf—Part 3

This is the third post in my series on how Fendt handles its rather large variability. As mentioned before, all of their tractors—eleven different models with countless variants—come from the same assembly line in Marktoberdorf. This includes small tractors that are just barely one meter wide and huge ones as you see here on the left. Imagine assembling motor bikes, cars, and trucks on the same assembly line, and you are getting close to the variability that Fendt has to deal with. Overall, this makes Fendt in my view one of the leading plants in the world in handling variability.

Variable Takt at Fendt in Marktoberdorf—Part 2

In my previous post I started to show you how Fendt uses the distance between tractors on their assembly line to manage their quite high variability. By changing the distance between parts on the line, you can adjust the takt time for each part on the assembly line, hence the name Variable Takt. But this still leaves a lot of variability, as not all stations will have the same identical workload. In this and the next post I will go deeper into how Fendt manages its variability. This will be good, since Fendt is one of the benchmark plants in the world in handling variability.

Variable Takt at Fendt in Marktoberdorf—Part 1

In this post I will look at how the tractor maker Fendt handles variability in its plant in Marktoberdorf, Germany. In my view, Fendt is one of the benchmark plants in the world in handling variability. In my previous post I looked at reasons why you may (or may not) leave one part empty on an assembly line with a part normally at every fixed interval. In this post I would like to expand on the idea of playing with the distance between parts to handle such variations in the cycle time, but with a focus on assembly lines where the interval between products can vary. We will look at how Fendt uses this to wrangle its variability.
