Objections To The History Of Quality As Told On The ASQ Website
5 years ago, I pointed out several omissions in the ASQ’s History of Quality pages, which have not been corrected. Specifically, I faulted them for ignoring the TPS/Lean approach to quality, the role of interchangeable parts technology, and the Roman philosopher Cicero, who coined the word “quality.” The first page, however, also contains what I think is an error of commission, where it credits the guilds of medieval Europe as precursors in the field, as follows:
“From the end of the 13th century to the early 19th century, craftsmen across medieval Europe were organized into unions called guilds. These guilds were responsible for developing strict rules for product and service quality. Inspection committees enforced the rules by marking flawless goods with a special mark or symbol.[…] Inspection marks and master-craftsmen marks served as proof of quality for customers throughout medieval Europe. This approach to manufacturing quality was dominant until the Industrial Revolution in the early 19th century.”
“[…]The principle of Jidoka applies everywhere, especially if we come down to its fundamental intent: preventing bad quality from going down the line and impacting the customer, understanding the causes of a problem as it happens, and giving the employee the authority (and autonomy) to stop the line when an issue occurs.”
“Six Sigma as a problem-solving methodology causes many hang-ups for Japanese managers. Many Americans seeking training in Six Sigma in Japanese organizations face resistance with little explanation as to why. This often leads to frustration and contempt towards management. They write off the Japanese resistance to the training as resistance to change, preventing growth and feeling unrepresented.

More Sophisticated Graphics In Today’s New York Times
“When the world looks at the United States, it sees a land of exceptions […] But why, they ask, does it experience so many mass shootings?[…] Perhaps, some speculate, it is because American society is unusually violent. Or its racial divisions have frayed the bonds of society. Or its citizens lack proper mental care under a health care system that draws frequent derision abroad. These explanations share one thing in common: Though seemingly sensible, all have been debunked by research on shootings elsewhere in the world. Instead, an ever-growing body of research consistently reaches the same conclusion. The only variable that can explain the high rate of mass shootings in America is its astronomical number of guns.”
The source for both charts is Adam Lankford from the University of Alabama. The charts Include countries with more than 10 million people and at least one mass public shooting with four or more victims.

Michel Baudin‘s comments: Six months ago, I was bemoaning the absence of scatterplots in business analytics and more recently complimenting the New York Times for the sophistication of its graphics. Manufacturing professionals should not be shy about using scatterplots, as they have learned to do in Middle School. Here, they are used to highlight outliers, which isn’t the most common application. What this article — and these charts — show is how the tool can be used not just to solve technical problems but to inform a political debate as well.-
