When someone mentions design for Six Sigma (DFSS), the initial thought usually turns to developing new, innovative products. While DFSS has its roots in product development, individual components of the toolset can be applied in a variety of ways.
Recently, the use of DFSS has exploded in…

It is widely known among quality and process improvement practitioners that the lack of a clearly defined scope or charter is perhaps the leading cause for projects not getting started or completed on time and within budget. What are other causes? From my experience, the No. 2 cause for restarting…

Analytic statistical methods are in very strong contrast with what is normally taught in most statistics textbooks, which describe the problem as one of “accepting” or “rejecting” hypotheses. In the real world of quality improvement, we must look for…

In “The Power of Observation—Part 1,” we learned that a good portion of problem solving should be devoted to a thorough understanding of what’s going on before any corrective action steps are taken.
In many cases, too much time is spent on proposing various solutions before the problem has been…

Some authors recommend that you have to wait until you have the range chart “in control” before you can compute the limits for the average chart or the X chart. Why this is not true will be the subject of this column.
To illustrate the issues we will once again use the NB10 data. The 100 values are…

I often get assignments at organizations where I am required to take aside a group of people, either within the building facility or off campus, to focus on issues or problems. Typically these groups spend a considerable amount of time to summarize and present a well-defined problem. The next step…

I discovered a wonderful unpublished paper by David and Sarah Kerridge several years ago (Click here to get a pdf). Its influence on my thinking has been nothing short of profound. As…

The most important element in producing a quality product or service is the attitude of the people doing the work—not only the worker—but the attitude of all levels of management. Employee attitude about the product, about the work, about the boss, and about the company will pretty well determine…

A $1 billion annual budget may sound ample, but a few years ago, the costs of services ranging from law enforcement to cleaning county buildings had squeezed the government of Erie County, New York, to its limit. Residents faced a painful choice: raise taxes or slash services. But Chris Collins,…
The emergence of green technology and increased environmental awareness has prompted a paradigm shift in the way companies think about the design of their products. Because robust designs mean creating products to meet customer and societal needs, it is important that all enterprises rethink these…

One of the most useful diagnostic tools for understanding what is going on in a process is the statistical process control chart (SPC). This is also a frequently misunderstood tool, and these misunderstandings lead to misdirected effort during a Six Sigma process, resulting in lost time and money…

Twitter is the latest new thing. Want to follow John McCain or Al Gore throughout their day? Easy. Just sign up to receive their tweets. While their tweets may provide insights, or just entertainment (Ashton Kutcher and 50 Cent also tweet), does Twitter have value for business management?
The…

When I first got into quality, I really hated verifying the effectiveness of actions taken to correct a problem. After all, I was young and inexperienced. All of the people whose actions I was verifying were older, wiser, and more experienced than I was. Who was I to say that their actions were…

Specific techniques for data collection, fundamental to accurate analysis, are sometimes overlooked in the need to see outcomes or trends in data. The lowly check sheet represents a critical tool in effective data collection if it is used correctly.
Because check sheets are such simple tools,…

With several generations of statistical process control (SPC) technology under our belts, it may be time to rethink how we apply SPC in the 21st century. Basic techniques have been practiced since the 1930s. Some companies will soon be able to say, “we’ve been practicing SPC for 100 years.”…

Charles Kettering, the famous inventor, once said: “A problem well stated is a problem half solved.” This implies that a good portion of problem solving should be devoted to a thorough understanding of what’s going on before any corrective action steps are taken.
In many cases, too much time is…

Profitable manufacturing requires efficiency, and this principle guides most (if not all) of our quality management systems (QMS). We’ve learned there’s little gain in correcting a production error…

Recently a strategy consultant was overheard saying she writes romantic novels. Look into many organizations and, although said in jest, it has more than a modicum of truth to it.
Don’t get me wrong. The high-level strategic plans are important and necessary. But, the devil is in the details,…

These days blogs and newspapers seem to make a daily reference to climate change, resource scarcity and security, the environment and the economy. It's overwhelming … and with the legions of experts in each of these fields, hard to see where one organization, let alone an individual, can make a…

Editors note: The author submitted this just days before he lost his job. What is ironic about this "rant," as Bruman puts it, is that it was written seven years ago. Do we never learn?
Recent months have brought disturbing news about the U.S. economy, the stock market, and business leadership…

Last month we showed the X chart in figure 1. The four lowest values and the three highest values were seen to be “outliers” when we looked at the histogram. When we fitted a bell-shaped curve to the histogram, the outliers corrupted the model and resulted in a poor fit. Yet we used all the data…
Here’s a story that proves once again that exciting quality applications can occur anywhere in the world.
BHP Billiton operates the EKATI Diamond Mine in Canada’s Northwest Territories, approximately 200 miles northeast of Yellowknife—just below the Arctic Circle. Arctic winter gear designed…

The current recession is the fifth in my working career. And it is beginning to feel like the worst. I can't imagine that any manager or improvement team member in any industry in any country isn't feeling a bit queasy at this point, as the world economy keeps recessing toward an unknown bottom.…
