Standard wisdom for creating a good material flow is to use FiFo lanes (First in, First out). In other words, the first part that goes into the line should also be the first part that comes back out. As such, FiFo lanes and its big brother, Supermarket, are essential for any lean material flow. However, some rules of wisdom can be bent and others can be broken. Here are the top five cases when NOT to use a FiFo lane. Continue reading Top Five Cases When NOT to Use a FiFo
FiFo lanes are an important tool to establish a pull system. They are often combined with kanban. However, while there is a lot of information on how to calculate the number of kanban (the Kanban Formula), there is very little information available on how large a FiFo should be. In my last post I talked about why we need FiFo lanes. In this post I want to discuss how large a FiFo should be. Continue reading Determining the Size of Your FiFo Lane – The FiFo Formula
FiFo lanes are an important part of any lean material flow. They are a very simple way to define both the material flow and the information flow. In this post I want to tell you why to use FiFo, how to use FiFo, and the advantages of FiFo, as well as show you a few examples of FiFo lanes. Continue reading Theory and Practice on FiFo Lanes – How Does FiFo Work in Lean Manufacturing?
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. Continue reading Ten Rules When to Use a FIFO, When a Supermarket – The Rules
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. Continue reading Ten Rules When to Use a FIFO, When a Supermarket – Introduction
