Posts related to different lean tools, often also known as the lean toolbox. Different methods that can be used to improve the shop floor, although it is risky to use methods on their own without a whole lean system.

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. Continue reading Cardboard Engineering – Alternatives

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! Continue reading Cardboard Engineering – Workshop

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. Continue reading Cardboard Engineering – Preparation

Mixed Model Sequencing – Complex Example Sequencing 2

In this seventh post on Mixed Model Sequencing, I will finish the sequencing of the more complex example with Product-Dependent Workload and Mixed Model Sequencing. This is now the tenth post in this series. I knew this sequencing topic was demanding, but even I am surprised how much there is to cover. Thanks for staying with me, and read on.
