The Danger of Management by Numbers

One of the main hindrances for proper lean manufacturing is, in my view, management by numbers. While few managers actively do management by numbers, a quantitative measurement is still often preferred. The problem is if you can measure the cost but not the benefits of something…which often happens in lean manufacturing. Now let me rant a bit…

The Boss Knows Best … or Does He?

Businessman is pointing at himselfThis post is on a topic you probably all have had experience with at one point or another (or even all the time) in your career. A superior makes a decision, and you are internally wincing because you know right away that it is a really bad idea. In this post I would like to talk about uncertainty and decision making, and how to make better suggestions. If you are a regular reader of my posts, you probably already know the answer: Involve the employees! This post is a continuation of my previous post on military leadership.

Work Improvement before Equipment Improvement

Maintenance Work in IndustryWhen improving a system, Western engineers love to take the technical approach and to optimize the machines and tools. However, at Toyota this is seen differently. At Toyota, they try to address a problem by first training the people, followed by improving the standards and the layout, before improving the equipment and finally twiddling with the design. Let’s have a closer look at how Toyota is approaching improvements.

How to Convince Your People to Do a Lean Transformation

Many companies want to achieve a lean production system. For this, these companies conduct lean transformations. And this in turn needs the buy-in of the people who will be working with the transformed system later on, usually the operators. However, a problem many lean transformations encounter is that … the operators don’t want to transform! This is of course a challenge. Let’s have a look at why this happens, and how you can prevent and overcome the issue.

Cardboard Engineering – Alternatives

Cardboard Engineering is a quick way to try out different configurations in reality. As the name says, this is done using cardboard. However, there are a few alternatives. Let me show you a portfolio of different ways to make cardboard models with (not only) cardboard, from ultra-cheap to very fancy. Please note that the fancier methods are usually not so well suited for layout optimization, but more for workstation optimization.

Cardboard Engineering – Workshop

Cardboard BoatIn my last post I talked about what you need for Cardboard Engineering. In this post I will show you how to do a Cardboard Engineering workshop. Spoiler: Keep in mind that the goal is not to just put something together but to try out different options (and I will repeat this a few times in this post). It is very easy to have fun with cardboard while learning very little about the problem you want to investigate!

Cardboard Engineering – Preparation

Cardboard Engineering (CBE, sometimes also Cardboard Modeling) is in general the building of models from cardboard.  These models are usually quick and inexpensive to build, but often not very durable. In lean manufacturing, these cardboard models are often workstations or entire assembly lines to test different concepts before building the whole thing in more expensive and time-consuming aluminum and steel. This allows faster and easier experimentation with different concepts to improve your production system.

Example of Problem Solving – Japanese Men’s Relay Team Rio 2016

Good problem solving can seriously help you with the performance in your plant. John Shook recently pointed out another nice example to me: the Japanese Men’s 4x100m relay team during the 2016 Olympics in Rio. They were the underdogs, with none of their team having ever run 100m in under 10 seconds. Yet they stunningly won the silver medal! They achieved this through good problem solving. Let me show you the details:
