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…

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…

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…

"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…

When organizations decide to deploy a Six Sigma initiative, there are several foundation stones required for a successful venture. One of those building blocks is leadership. From executive-level support to assigning champions and choosing the right projects, leadership is critical for Six Sigma…

We examined the practices and major problems that can easily occur in the use of balanced scorecards in the June 3 issue of InsideSixSigma. Now let’s look at why attention to causal event analyses can improve the future performance of any process. Often, this traditional method fails to make metric…

Over the years, scorecards have progressed through many changes, good and bad. Although scorecards often evolve into a meet-the-numbers game, regardless of the consequences to an enterprise as a whole, restructuring can produce dramatic improvements for any organization. This results in counter-…

Manufacturing firms intent on capturing and distilling rich streams of data will find them. Companies will often look at a capability maturity model (CMM) in rows and columns—a format common across many industries and many applications—in Excel. Most data dumped from a database end up in a grid,…

Few process improvement topics generate more questions or may be least understood than design of experiments (DOE). This is regrettable as DOE is probably one of the most important activities—after the charter definition—that a manager/Black Belt will be performing during the Six Sigma process.This…

Six Sigma promoters and innovation advocates have emerged as opposing camps in the battle for tool supremacy in the organization improvement wars. As Business Week said in “Six Sigma: So Yesterday?” and “At 3M, A Struggle Between Efficiency and Creativity,” which described how GE, Home…

In Part 1 of this article I discussed Six Sigma failures and the fundamental flaws in the term Six Sigma, as seen in figure 1 below, which highlights the flaws in the hundreds of Six Sigma web sites displaying the nonsense of out-of-control processes that are the result of the claimed “unavoidable…

Six Sigma captured the imagination of CEOs around the world. There have been many claims of its successes yet these have at least partially been attributed to the Hawthorne Effect, which implies that if enough money is thrown into any methodology, at least some short-term results can reasonably be…

With all the emphasis today on quality, and studies showing that quality is very important to the leaders of American business, why are so many organizations struggling to achieve and sustain quality systems? The answer is that managers have been inundated for 20 years with a parade of quality…

For quite some time a major question has been cropping up in my mind: Is Six Sigma’s application in software development as effective as it is in the manufacturing industry?The answer is “No.” The savings and benefits that occur in the software industry due to Six Sigma and other process-…

The manager of a local grocery store is having dinner with his statistician friend. The store manager tells his friend about a certain cashier who is stealing from the company.
The manager is frustrated because he thinks he knows who the thief is, but can’t fire the miscreant because the employee…
There’s a certain manufacturer makes carbon-based friction material in the form of a disk. A press and die are used in the final manufacturing operation to cure the carbon material into a functioning friction pad. Peak temperature uniformity is a critical characteristic during the cure…

Some folks like to use control charts to analyze gauge study results. When using a control chart in this manner, one can assume that the chart should represent a series of gauge studies conducted over a period of time. In this example, let’s say that each morning a gauge is verified by…
