In this series on how to understand a shop floor, I talked a lot about the physical shop floor—which in my view is the more important part. However, as mentioned in my last post, looking at already collected data also gives a lot of insight into the shop floor. Depending on the aspect you are interested in, data may be the only way to grasp the situation. Hence, this post will look deeper into how to work with data to understand the shop floor.

Different Aspects of Seeing a Shop Floor—Gemba vs. Data
In my last three posts I showed you how I look at shop floors, starting with some general guidance (FOCUS!) and going into detail through the different aspects of what I try to observe on the shop floor (5S, visual management, waste, unevenness, overburden, and safety). This usually gives me a reasonable overview of what is going on on the shop floor. However, this is not all I do. For projects, I may have project specific observations (e.g., when I do a SMED project, I observe in detail the actual changeover). But beyond that, there is another source: the available data! Hence, this post will compare information you observed yourself on the shop floor (the gemba) vs. data obtained by others or by computers.
Different Aspects of Seeing a Shop Floor—Unevenness, Overburden, and Safety
This post continues my series on how I try to understand an unfamiliar shop floor. In the last post I talked about how to see visual management, 5S, and waste. These are usually easy to see. This post continues with unevenness, overburden, and safety, which are usually harder to observe.
Different Aspects of Seeing a Shop Floor—Visual Management, 5S, and Waste
In my last post I looked at some general tips on how to see the shop floor. Most of them involve focusing on the right areas of the shop floor, and avoiding interesting but not relevant technical details. This post will discuss different aspects that can be observed. Here, too, try not to see everything at the same time. This will make you like a young tiger hunting ducks; if he tries to catch them all, he will catch none.
Different Aspects of Seeing a Shop Floor—Introduction
I am in the lucky position of seeing a lot of different shop floors through my work. This requires me to quickly understand what is going on on the shop floor and to estimate how well the shop floor is managed. What my hosts tell me and what I see unfortunately does not always match. In this series of posts I would like to go through my steps for understanding the shop floor to form my own opinion on the production system.
One Up One Down – Approach to Manage Manual Production Lines
Production lines have fluctuations. Sometimes production takes longer, sometimes shorter, than the average. This makes the line balancing tricky. Besides using a simple buffer between workstations, it is also possible to adjust capacity. Other approaches I have written about include the rabbit chase and the bucket brigade. Here I present a variation of the bucket brigade called “One Up One Down.”
Toyota Standard Work – Part 3: Standard Work Layout
This post is the third in this series on how Toyota plans standard work. The first one was the production capacity sheet to define what capacity you have available. The second one was a standard work combination table to define when the operator is doing what. Finally, the third of the “famous three slips”, presented in this post, is a standard work layout sheet to help the layout and arrangement of the machines.
Toyota Standard Work – Part 2: Standard Work Combination Table
Toyota has a nifty way to plan the work of an operator using their standard work charts. In my last post I explained the production capacity sheet to define what capacity you have available. In this post we will talk about the second of the “famous three slips”, the standard work combination table to define when the operator is doing what. A subsequent post will show a standard work layout sheet.
