One popular approach to battle waste is to streamline changeovers. Changing machines from one set-up to another is often a time-consuming exercise. Hence, in lean manufacturing, reducing changeover times is a well-known method for improving efficiency. In this post, we will go through the basic approach of improving changeover time, also known as quick changeover or single minute exchange of die (SMED).
Whenever you work with people, the impression you make on these people is important. Your clothes and behavior have a great influence on this impression. This post discusses strategies for your appearance to increase your chances of success on lean manufacturing projects.
If you work in manufacturing, sooner or later you will find someone who claims that lean manufacturing is all about Zero Defects. Or Zero Inventory. Or Zero Lead Time. Or Zero Whatever. This is bollocks! Zero Defects was a management fad from the 1960s that pops up regularly every now and then again. In this post we will look at what Zeros there really are in lean manufacturing – if any.
During my last trip to Japan, I finally took videos capturing the Japanese Pointing-and-Calling standard. Pointing and calling is a safety standard that started with Japanese train operators but now is widely used in industry. The idea is that whenever you confirm something, you not only look at it, but also point at it and call out your observation.
Lean manufacturing pull systems use both FIFO lanes and supermarkets to manage the material and information flow. In my previous post we covered the basics about supermarket and FIFO lanes. Now we go into details about the ten rules when to use a supermarket instead of a FIFO.
It is generally accepted knowledge that a lean manufacturing pull system uses both FIFO lanes and supermarkets to manage the material and information flow. However, there are few guidelines on when to use a supermarket and when to use a FIFO lane. This post is the first of a two-part series that will give ten general rules of thumb for when to use a supermarket instead of a FIFO lane. The second post will go into more detail about the ten rules.
Due to the popularity of my lean tool kit, I present you here my extended lean tool kit. These are items and tools that I frequently use for lean manufacturing on the shop floor, but as opposed to the items from the lean tool kit, I bring these along only if I know I will need them.
Lean happens on the shop floor. When working hands-on in manufacturing, there are a number of items that can help you. Throughout the years I have optimized a small lean toolkit that I bring with me for my everyday practical work. Here are seven gadgets that help me to do lean on the shop floor.
