Standards are one of the backbones of lean manufacturing. For a standard to be good and used consistently, it should be self-explanatory. Additionally, you should understand it well enough to easily recognize deviations from the standard. I would like to give you an example of how my thought process works when exploring a standard.
In my previous posts I talked a lot about internal milk runs. However, you can also have milk runs externally across multiple suppliers and plants. There are a few things to consider that are different from the internal milk runs. Let me elaborate …
After discussing a lot about the milk run, its use, and its calculations, here is a post on a number of remaining frequently asked questions. Many of them are pitfalls, where it is easy to make a quick wrong guess (e.g., two milk runs on the same route will not halve your inventory at the assembly locations). Let’s get into more details.
In this post I will discuss the layout of the milk run as well as the space on the milk-run train, and other topics. It is a continuation of the previous post on the milk-run calculation. Let’s continue.
After all the theory on how a milk run works, it is finally time to calculate the quantitative details of the milk run. Since this takes a bit longer, I have split the calculations into two separate posts. Well, here we go!
In this second post on the topic of milk runs, I will look at the organizational issues around the milk run: what kind of transport can you use, and what should the source warehouse be like. I will also talk about optional extras like repacking or kitting. Let’s start.
Milk runs are a popular concept for material delivery within a plant and even across multiple plants. It is very much based on the philosophy of pull, keeping inventories down, and making material supply easier.
However, it is only suitable for mass-produced goods, or more precisely for identical components and identical parts, even if they go into different product variants. Additionally it can also be used with kitting. This post starts a series on the topic of milk run with an introduction to the topic.
