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…

Command Medical Products of Ormond Beach, Florida, is a medical-device manufacturer that designs, manufactures, assembles, and packages disposable medical devices such as intravenous tubing, blood bags, IV bags, and catheters. Command Medical initiated its journey into lean manufacturing to…

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.…

A colleague of mine made an interesting point about how we teach and learn experimental design techniques, and I thought I'd explore the subject further. He observed that the order that we teach statistics is almost exactly opposite of how one would actually use them. So this month I will describe…

One of the most frequent questions I get from Black Belts and Green Belts I train is about the characteristics of a good Six Sigma project, particularly a first project. Define, measure, analyze, improve, control (DMAIC) is a procedure that is useful for certain types of projects and terrible for…

Those best adapted to particular conditions will succeed in the long run. This idea was invented by Herbert Spencer in Principles of Biology (University Press of the Pacific, 2002) to describe Charles Darwin's theory of natural selection of living species.
By the early 1900s, this insight was…
Criteria changes and lean Six Sigma
In these difficult economic times, organizations are looking at all possible means to operate profitably. As demand for products and services drops and customers expect the lowest possible price, organizations are feeling urgent pressure to cut costs as a…

Many people go through a point in their lives where they question the beliefs they hold most dear. Then there are those who question the entire basis for statistical process control (SPC) once they have learned the statistical basis for them. I can’t help you with the former, but I have something…

As you read this you will, no doubt, have already made (and perhaps broken) your New Year’s resolutions. I’d like to propose one that we, as business leaders, have a special responsibility to follow and whose failure we hear about in the news almost every day.
Of course, I’m talking about…

During a recession, the concept of lean should make absolute sense to an information technology (IT) manager who wants to pursue every channel to increase efficiency and productivity.
We have seen a procession of quality standards adopted by software services organizations in the last two…

There are several issues about the Six Sigma approach to quality that bother me. First, Six Sigma is a performance standard that hardly anyone can understand. Secondly, it’s an engineering approach to quality management. It’s more of a defect-management program than it is defect-prevention.…

The cost of doing business is rising dramatically. Included in this is the cost to recruit and hire talent to join your team. It’s estimated that the total cost of one hire can exceed $30,000 when relocation and set-up expenses are included. That cost is minimal compared to the lost opportunity…

What purpose, if any, does Six Sigma serve in economic downturns? Full disclosure: I teach and consult in Six Sigma and related areas, and you’re reading this article because you’re interested in Six Sigma, so we may not be the most objective people to assess this, but in this article, I will do…

Organizations embarking on the journey to process excellence have much to gain if appropriate actions are taken in the early stages of deployment. A key principle of Six Sigma is that defects identified and fixed upstream will result in significant leverage and benefits downstream. Similarly, the…

Today’s hyper-competitive business environment is creating a need for even more new products, new services, and new processes. Design for Six Sigma (DFSS) offers a generalized and effective approach for designing new products and services from the ground up. One of the more popular DFSS…

By the time you read this, the amazingly long U.S. presidential election will be over. All U.S. citizens will be wandering around aimlessly bumping into objects, pressing their hands to the sides of their heads as the indignation poisons slowly leave their bodies, leaving them with a hangover-like…

A physics exam question asked students to describe how they would use a barometer to measure the height of a skyscraper. One student who failed the test contested that his answer was correct. He was given a second chance to defend his position, verbally, to the professor. When the student didn’t…

Every once in a while, people ask about acceptance sampling plans and I get all riled up. We all know (especially in this political season) that humans are addicted to their indignation high, so here’s your fix for today.
Back when defective products and services were considered inevitable, the…

Question: What is the proper way of wearing a Black Belt once you’ve earned it?
Answer:
as in ….
I’m a changed man. I’m an American Society for Quality (ASQ)-certified Six Sigma Black Belt. To obtain the ASQ Black Belt, I had to pass a test and then show proof to someone within…

"We have had a series of power outages even though we have central and local uninterrupted power supply (UPS) systems. This disruption causes a loss of service to our customers. While we don’t necessarily lose data, it’s an irritant, and also results in loss of productivity. Perhaps we could…

In the Six Sigma world, we give a lot of lip service to the importance of the customer; we even have an official name for it—voice of the customer, or VOC. The problem is that many businesses don’t really have a good system for giving the customer what they ask for, much less one for listening to…
