On a modern shop floor, you will find lots of data and documentation. These are quite useful to track and improve the situation in the operations. Many of them are quite nicely printed charts, diagrams, and tables of key performance indicators (KPIs). However, when I look closer at them, I often find that they were last updated six months ago, or even more than one year ago. That is useless in practical terms! You need up-to-date information if you want to manage a process. For this, entering data by hand is most useful. In this post I will discuss different advantages of tracking data by hand on the shop floor.
The FiFo Calculator – Determining the Size of your Buffers
In my previous post, I discussed how to Determine the Size of Your FiFo Lane – The FiFo Formula. My preferred method is still an expert estimate. However, if you are interested in the math, here is a small JavaScript calculator that estimates a FiFo size for two processes.
Visual Management during World War II – A Visit to the Lascaris War Rooms in Malta
For larger improvement projects with a dedicated project team, there is frequently a “war room,” a conference room where all the project-related information and performance measures are kept. The name sounds cool and gives a certain air of focus to the project.
The name, however, comes from war rooms for real wars. Recently I had the chance to visit the Lascaris War Rooms in Malta, where I was able to see many tools and practices that are still common nowadays in manufacturing and project management.
Happy 1st Birthday AllAboutLean.com
AllAboutLean.com is one year old. Exactly twelve months ago I started this blog on September 1st with my first post, New Professor, New Blog. Since then I have published fifty-six posts. Time to have a look back. What were the most popular posts? How did visits to my blog develop? What is the outlook for the future? And what is there already in the pipeline that will appear soon on AllAboutLean.com?
Determining the Size of Your FiFo Lane – The FiFo Formula
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.
Theory and Practice on FiFo Lanes – How Does FiFo Work in Lean Manufacturing?
Corporate Culture on Quality Starts at the Top – A Small Anecdote on Organizational Blindness
Quality starts at the top with management. Top executives like to talk about quality, but employees below usually know very well if the manager only talks the talk or also walks the walk. Words are cheap. Quality (and pretty much everything else that is important) requires attention by management.
Facing Change in Modern Manufacturing Systems – The Difference between Flexible, Agile, Reconfigurable, Robust, and Adaptable Manufacturing Systems
The speed of modern business is continually increasing. Product life cycles of cars and mobile phones are decreasing, and customer demand is more volatile. Gone are the days of Henry Ford, who produced his Model T for almost 28 years without much change. Modern manufacturing systems need to be prepared for a constantly changing environment. The challenge has been realized for quite some time now, and there are a multitude of expressions related to this problem. This post will discuss many of these terms related to the challenge of change.
