Lean was initially started in manufacturing and production departments, and various efforts are being made to apply its principles in service industries. In a highly industrialized world spurred by high technological changes, businesses are forced to change their strategies to a more lean way…

As part of a volunteer team that cleared a walking trail in my neighborhood, I helped to shovel a straight path through a small berm. Seeking to solve another problem at the same time, a member of the party started to use the dirt he removed to fill in a nearby puddle on the trail.…

It’s New Year’s resolution time. Many of the things we resolve to do in the New Year are measurable—lose weight, run farther or faster, quit smoking, do more of some things and less of other things. All can be measured. But how do you measure success (or failure)? What do you measure…

Years ago, when my kids were in middle school, I volunteered as a coach for the Future Problem Solvers, a competitive academic program designed to help young people develop the creative thinking skills they will need as tomorrow’s leaders.While the bulk of the time was spent teaching…
QC 080000 IECQ HSPM calls for a process management approach to the management and reduction of hazardous substances in products and processes. It utilizes familiar conventions from the ISO standards world, while calling for a full review and understanding of the technical issues that…

In the past several months, registrar auditors strongly recommended to three former or current clients that they develop and install turtle diagrams for each of their processes. Two auditors from one registrar actually taught a former client how to develop a turtle diagram during a surveillance…

Six Sigma was officially launched January 1, 1987, at Motorola, and it took more than nine months to make Six Sigma real. Twenty years later, Six Sigma has grown from a good baby methodology into a mature system that affects thousands of corporations and millions of people and that saves billions…

Those of us in the acting profession hear those words regularly at the end of a particularly grueling day from a director attempting to extract perfection from a group of actors. (I’ll discuss my own celluloid exploits later).It’s appropriate to utter similar words at the end of 2006—a grueling,…

In our increasingly wireless world, the air is chock-full of electromagnetic signals carrying data from one place to another. Yet, while new wireless technologies advance our options in security, commerce and entertainment, they also produce interference that may cause problems for…

In this installment of my arbitrary and capricious list of the Top Ten Stupid Six Sigma Tricks (SSST), let’s talk about an error that is perhaps less frequently made now than it has been, but is still common. I call this error SSST No.6, constraining your improvement activities to…

If you read my previous two columns, you’re well educated on the top 10 mistakes that manufacturers make when implementing statistical process control (SPC). Several of these mistakes are indicative of what I call the “check-box mentality.” This mentality is typically the result of an…

Continuing last month’s topic of temperature effects on measurements, what about temperature compensation? Some measuring systems claim increased accuracy with the usually optional temperature compensation. What’s that? What’s it supposed to do? And does it do what it claims to do?
Remember that…

The adage “The pen is mightier than the sword.” is hackneyed, accurate and profound. I’ve done several pieces on the influence of words. The simple fact is that how we say something often matters as much as what we’re saying. It’s a wondrous phenomenon, one that is too often taken for…
Last month’s column provided background on the International Electrotechnical Commission, one of only three standards-setting bodies recognized by the World Trade Organization. Readers may have asked, “So what?” The answer is that one of the three “schemes” within the IEC has provided…

Editor’s note: We’re intrigued by this article, in which the author posits the idea of "Theozen," the author’s term for a God-based approach to quality.
Most of us have some sort of spiritual belief, whether it’s part of an organized religion such as Buddhism, Christianity, Hinduism, Islam,…

Most quality management systems don’t produce the desired results because of the way companies use it to affect their bottom line.
A QMS is often considered to be a burden, and there’s apathy in all levels of the organization toward quality. ISO 9001 systems, for example, are considered to be paper…

As the holiday season approaches, several inevitable occurrences will try our patience. Along with people jostling in lines, the NASCAR-like jockeying in the parking lots, out-of-stock merchandise and interminably long lines for Santa, we also have to endure the banes of holiday…

Déja vu After the 2006 primary elections in the United States, a local newspaper article headline read, “Computer ballots in stage of ‘trial and error.’” Although elections are critical in a democratic society, electronic voting that isn’t transparent has been introduced with a trial-…
Georgia Tech postdoctoral fellow Jean-Francois Masson holds a microelectrode modified with a biosensing layer capable of measuring adenosine triphosphate (ATP), a chemical involved in energy transport in humans. It’s of interest to medical…

Last year I had the good fortune of doing some consulting with B&C Specialty Products in Hopeulikit, Georgia. B&C does light manufacturing, primarily plastic molding and assembly, and they also distribute imported products produced by companies in the Far East. They have about…

The Stupid Six Sigma Tricks countdown continues this month with an increasingly common error: “Inadequate Infrastructure.” By infrastructure, I mean those systems and processes that need to be in place in order to support the objectives of Six Sigma. Regardless of how you define Six…

Following last month’s excellent article "Management and the Bhagavad-Gita" by M. P. Bhattathiri, Quality Digest got several requests for an article discussing how the Christian bible might also be used in an organizational context. In the following, Quality Digest editor in chief, Dirk Dusharme,…

Slow monitors that don’t pick up the exact end-point when a part is seated properly can hamper high-volume press-fitting operations. This process-control problem is especially widespread in automotive-powertrain assembly. A transmission, transfer case or differential can contain four to…

This is the first “Measurement Matters,” a column that will show how much measurement matters in achieving and maintaining quality, especially in manufacturing. I will cover topics such as types of measurements and measurement devices, how measurements are made, what can be done with the…

The local environment can be an important factor in the quality of measurements. No matter what is being measured, the higher the resolution of the measurement (the finer the detail), the more significant the effect of environmental influences can be. The measurement you’re after is one…
