Growing up, occasionally, a family vacation would include a factory tour related to my Dad’s work. He was providing some management or engineering consulting and took the opportunity to check in on progress and visit the gemba. Here is a photo from one of those tours (in Nigeria, I think). My brother and Mom are visible in the photo.
The tours (which were not a very common occurrence) were quite enjoyable and interesting. Though I really didn’t like how noisy the factories were. Seeing all the machines and vast scale of the systems was quite a change of pace and added some excitement to the vacations (that often were already pretty exciting). I remember we also visited some factories in Kenya (in between seeing the game parks).
On this tour we found a bit of visual management showing which side of a crate should be on the top.
