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.
Consistency at Toyota – The Board of Directors of the Toyota Motor Company
The Toyota Motor Company (TMC) is one of the most well-managed firms in the world. Among multinational corporations, it is probably the most famous one. Since its founding in 1937, TMC has continuously improved. The question is, how did Toyota do that? What does Toyota do differently from other companies, who stumble from one problem into the next? I believe the corporate culture and style start with the behavior at the top. Hence, in this post I will look at the board of directors of TMC in more detail.
Japanese Standard Pointing and Calling (Video)
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.
Value Stream Mapping – Why to Start at the Customer Side
Have you ever been to a value stream mapping workshop? If so, you may remember the insistence of the coach to start any mapping activities at the customer side (the end) and then work your way backward (to the beginning). Yet, if you would ask why, you would get only some vague answers about this way being better, more lean, or just the way Toyota does it. In this post I want to go into more detail about whether it may be beneficial for value stream mapping to start at the customer side, and why.
Simple Triangle Kanban System for Office Supplies
Kanban systems are a huge help in industry, ensuring a steady availability of parts and products without excess stock. However, Kanbans are not necessarily limited to industrial use. In this post I will describe a simple Kanban system for office supplies. This system is also sometimes known as triangle kanban. One benefit of this system is that it will improve the availability of pens, paper, and other supplies. However, a second major benefit is that this provides a risk-free opportunity to train your people in creating and using Kanban systems.
Ten Rules When to Use a FIFO, When a Supermarket – The Rules
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.
Ten Rules When to Use a FIFO, When a Supermarket – Introduction
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.
Hell is Other People – Workplace Conflict between Managers and the Managed
Throughout the history of industry, there has been a constant conflict between managers and subordinates. For some reason, we just don’t get along well with each other. Or, as philosopher Jean-Paul Sartre phrased it, “Hell is other people.” In fact, large advances in mechanization and automation were due to managers wanting to take power away from workers or to get rid of workers altogether.
