Marbles and batch size

Last weekend our family visited the model railway museum in Kouvola, Finland. It is a very fascinating place with all the small trains travelling in a miniature village. However, from a certain point of view the most interesting thing in the museum is a marble race game. My sons played with it and tried different ways to add new marbles. After I had watched that for a while I thought that we should record an experiment. Here's a short video I made about it:

So why share this? Well, I guess all of you who are familiar with things like batch size, flow, and kanban know what I mean. For those of you who aren't here are a couple of questions you could ask yourself:
  1. What are the marbles in your organization?
  2. Do you know what your batch size is?
  3. Are the marbles in your organization rolling or do they get stuck too often? What might be the reason for that?
