Of the 100 companies named to Fortune magazine’s list of the world’s largest companies in 1956, only 29 of them remain on that list today. Many lost their way because they failed to recognize the changes taking place, or were too big to react quickly enough to shifting market conditions.…
It seemed like a good idea at the time to Jon Shupenus, U.S. Army Forces Command’s process improvement specialist and lean Six Sigma Black Belt. Shupenus was attending a Department of Defense performance management seminar in 2010 when Kirk Nicholas, director of the Army’s continuous process…

I greatly believe in training. I have been fortunate to work in businesses that also believed in having trained and qualified professionals in their organization. I have personally and professionally benefited from that philosophy, and I have gained new knowledge as a result.
Since graduating from…

Often a firm is confronted with the key question of whether the quality of its products and services should be improved. For many readers, the question may even seem illogical: How could it not be beneficial for a firm to improve the quality of its products and services?

As we continue our sabbatical journey, more opportunities for the improvement of management practices continue to appear. This month, the overriding theme that I have observed is the lack of front-line performance that seems to be a result of the system. I have been reminded of the many times we as…

It seems the most popular way to improve a process these days is by applying the glorious "Lean Toolkit." Many companies focus on learning and implementing process improvement practices introduced by Toyota without realizing the same success that Toyota achieved. How can it be that so many firms…

Every once in awhile people will ask me to (discretely) evaluate a kaizen event team’s effectiveness. I don’t necessarily relish doing that when it is intended for the purpose of team comparisons, but it’s not an unfair request from senior leaders.
Someday, I should probably try to pull the…

There are two ways to slide easily through life: to believe everything or to doubt everything. Both ways save us from thinking. —Alfred Korzybski

The first part of this article illustrated the kinds of problems that can happen when data from non-normal processes are plotted on traditional control charts, and when traditional process capability assessments are applied to these data. This second part will show what to do about these problems…

My March 30, 2011 article ended with wisdom from Yogi Berra as a warning to the quality profession. Some prickly reactions to it got me thinking about the last 30 years or so of quality improvement.

Gary was a talented, creative welder with an idea that made perfect sense to him but was not supported by conventional measures. Gary was determined to implement his idea and pressed for a closer evaluation by his supervisor when the idea was not immediately accepted. This was Gary’s idea:

Problem solving is much more than arriving at an elegant solution. It is a twofold progression that includes problem resolution and solution implementation. Six Sigma and process improvement methods are examples of this sequenced approach to developing and deploying a remedial action that improves…

Story update 4/13/2011: We corrected a misquote regarding who first said, “As goes GM, so goes the nation.”Every day, it seems, business as usual gets a bit more unusual. I’ve been haunting the news portals and blogs, curious to see how experts are viewing potential supply shortages following the…

How many times have you heard, “Lean is in and Six Sigma is out” from a colleague? The funny thing about this is that I used to hear the same thing 23 years ago. Only then it was, “Lean is in, and quality improvement teams are out.” Little has changed since then. Everyone is looking for a simple…

Read this. It won’t be a waste of time.

There are four statements regarding control charts that are myths and in my experience, just refuse to die. The next time you're sitting in a seminar and someone tries to teach you how to transform data to make them normally distributed, or at any point during the seminar says, “Normal distribution…

An excellent article by Donald Wheeler on the economic cost of quality, “What Is the Zone of Economic Production?” gave me pause to consider the strategic implications of reducing the costs associated with poor quality. As Wheeler pointed out in his article, there is an economic zone of production…
