On Christmas Eve 115 years ago, Joseph Moses Juran (December 24, 1904 – February 28, 2008) was born. He was a highly respected and very influential quality guru. His work not only helped the United States, but also changed Japan, possibly even more than that of his better-known colleague Edwards Deming. Time to look back on his life’s impact on the world.
Lean has a bunch of advanced but good tools for material delivery, like Just in Time, Just in Sequence, and Ship to Line. Using them is much easier on short distances and with short delivery times. Yet, sometimes you just don’t have the option of short delivery times. This blog post deals with the issues related to long lead times and delivery times.
Often, implementing “lean” means management is picking the latest lean-related buzzword and telling their people to implement it. This is wrong on so many levels. For one, a lean project should always start with a problem, not a solution. On another level, good manufacturing is all about the nitty-gritty details.

This includes the traditional seven types of waste – of which I am a big fan. For completeness sake I also included a lot more types of waste I have come across in industry. However, you have to decide yourself if these additional wastes are not themselves a waste.
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.
One of the main aspects of lean manufacturing is quality. This post discusses the differing attitudes regarding quality in different corporate cultures. In particular, the Toyota brake recalls and the GM ignition recalls are compared.
There are thousands of things to see during a plant tour. However, if you really want to know how good the plant is, there are a couple of tricks on what to watch during the tour. This post will give you a few quick but reliable metrics to estimate the performance of the plant.
The Overall Equipment Effectiveness (OEE) is by far and wide the most lied-about and fudged measurement on the shop floor, both intentionally or by accident. This post tells you the top three different ways how an OEE is fudged, so you know which OEE to trust and which one not.
