What Is the Logic Behind a One Tail Defect, Or Is it That This Difference Is Negligible Beyond 3.5 Sigma?

Published:

Of considerable interest, this concept often mystifies newcomers to field of Six Sigma. As you already surmised, the referenced charts rely upon the assumption of a unilateral specification (single-sided performance requirement). From a defect accounting point-of-view, it should be fairly obvious that a unilateral (one-sided) specification must be treated as a single defect category. However, a bilateral (two-sided) […]

How can Six Sigma be integrated with ISO?

Published:

Imagine working for a corporation that is operating at an overall quality level of about Six Sigma.  In terms of capability, this means that the company would be about 1,800 times better than the average organization (about Four Sigma).  So, what would such a difference be like?  If it existed, what would not need to […]

Where did the name "Six Sigma" come from?

Published:

In my recollection, two recurring questions have dominated the field of six sigma.  The first inquiry can be described by the global question: “Why 6s and not some other level of capability?”  The second inquiry is more molecular.  It can be summarized by the question: “Where does the 1.5s shift factor come from – and […]

Can you discuss a few of the common problems related to project selection and how they can be addressed in a large service organization?

Published:

The following is a list of some “big dos.”  Just flip things around to answer your question. 1) The project targets only one CTQ (for purposes of improvement).2) The target CTQ should be measurable – conveniently and economically so.3) The CTQ should have a well-defined set of performance standards.4) The CTQ should not involve destructive […]

I am a consultant with 3 years of quality experience. How should I go about earning a Six Sigma certification?

Published:

By the nature of your question, I would assume you are a quality professional of some type or form – especially now that you provide consulting services within this arena.  I find it most interesting that you have only three years experience as a quality practitioner, but now serve as a quality consultant.  Given such […]

A good number of management systems are available in addition to Six Sigma. Can a company survive with only one?

Published:

Today, very few corporate executives believe that TQM is a viable system of business management.  To this point, a 1996 study titled “Measuring Performance After Meeting Award Criteria” was published in Quality Progress magazine.  The conclusions were quite apparent – the impact of TQM practices may not be nearly as significant as some think.  After […]

Why are some people made to feel inappropriate for desiring a Six Sigma certification?

Published:

Having originated the term “Black Belt” at Unisys Corporation in 1986, pioneered its development at Motorola’s Six Sigma Research Institute in 1990, focused its purpose at Asea Brown Boveri in 1993, delivered its promise at Allied Signal in 1994, and set its destiny at General Electric in 1995, it should stand without saying that this […]

What is the main difficulty experienced during deployment of Six Sigma in government?

Published:

The main difficulties can be extracted from the following assertions: 1) Everyone is a “decision maker,” but every decision requires consensus. 2) The purse strings are many, and so are the knots. 3) The phrase “just around the corner” means there are more corners. 4) The words “yes” and “no” are fully interchangeable — and […]

If you are only allowed to select a handful of tools in the six sigma tool box, what are the tools you will select as the key ones?

Published:

It is now late in the evening as I prepare an answer to your question.  Maybe it’s the fatigue after a day of providing answers or perhaps it’s the nature of the question, but what really grabs me about your question (perhaps in the wrong way) is the word “tools.”  From a different perspective, I […]

What do you do in automated manufacturing environments, hospitals, telecom centers or data centers where equipment uptime is so critical?

Published:

Based on the elements of your question, I would say that your problem could be readily shaped into a Black Belt project.  I would assume that a Pareto analysis has already been conducted. As a more advanced diagnostic, you should consider employing a multi-vari chart.  Although simple in nature, such a chart has considerable power.  […]

How can I make my organization see that Six Sigma has significant benefits?

Published:

As most of the world already knows, nothing sells better than sex, money, and hope.  Since sex would appear to have little to do with Six Sigma, we should focus on the merits of money and hope.  Most generally, top management gains “hope” when it smells “money.”  This principle seems to hold true regardless of […]

Could you explain the best way to predict the outcome of a process in the future?

Published:

Reference the quality literature on statistical process control, also known as “SPC.”  There are many excellent books on the subject, particularly the one by “Grant and Levenworth.”  Process improvement and optimization is often accomplished by way of statistically designed experiments, or “DOE” as it is known.  To this end, the work of “George Box” is […]

I am working on a six sigma project via teleconferencing with very minimal management support. What will it take for me to be successful?

Published:

No, this is not a challenge; it’s called “dreaming.”  You have to be joking – a six sigma project (over the phone) with little management support – and you are asking me if it will be successful?  My best advice is for you to; a) approach your management in a courteous way, and then b) […]

How can we improve the growth and acceptance of Six Sigma?

Published:

We must always remember that the power brokers within and external to a corporation are the ones who render judgment about the success or failure of some initiative. Simply stated, the power brokers are only concerned with one matter – demonstrated results that are overtly visible and economically aligned with larger aims, not hidden somewhere […]

How does normality of the data impact the process performance?

Published:

First, there is a great deal of literature on this subject – find it and read it.  However, there is no substitute for direct experience.  Of course, this is directly related to the old saying “we learn by doing.”  Along these lines, I would strongly recommend that you further your Six Sigma training and education […]

How can employees be motivated to do projects?

Published:

From my perspective, this is not a Six Sigma problem.  However, it does seem to be a management problem.  The motivational issue will likely disappear with some proactive leadership.  The difficulty you are have in relating your issues to the bottom line is likely due to the nature of your accounting system (i.e., a mismatch […]

What references would you suggest to learn about Six Sigma via self-study?

The following references will provide a very nice overview of the field – from general theory to in-depth case studies: 1) “Six Sigma: The Breakthrough Management Strategy Revolutionizing the World’s Top Corporations” by Mikel J. Harry, Ph.D. and Richard Schroeder, Doubleday 2000. 2) “Jack Welch and the GE Way: Management Insights and Leadership Secrets of […]

How many Black Belts are there and how can it improve my career?

Published:

Sometime in the not too distant past, I recall that Quality Progress magazine reported on a study that considered annualized Black Belt earnings.  For the exact information on this, you would obviously have to reference the original article.  However, my less-than-perfect memory seems to inform me that a Black Belt earns about $9K(US) to $10K(US) […]

If a Project Doesn’t Meet the Six Sigma Level (as Calculated on the Sigma Calculator on This Site), Is it a Six Sigma Project?

Published:

Seems to me that you have described a traditional quality improvement project. Based on the elements of your question, it is my understanding that: 1) Each “drawing feature” constitutes a “defect opportunity.” 2) The customer’s minimum expectation was a quality level of .99, per feature. 3) The pre-project quality was found to .995, per feature […]

How significant is benchmarking in an overall Six Sigma approach?

Published:

I assume that you are referring to the “quantitative” variety.  In this regard, I believe that benchmarking is a highly valuable activity.  For example, consider the “sigma-tizing” of a business.  Let us suppose a certain corporation discovers that it is a 3.5 sigma business.  Now suppose that the same company finds one of its competitors […]

What are the merits and demerits of integrating Six Sigma with Theory Of Constraints, benchmarking and Lean technologies?

Published:

The attempted integration of Six Sigma with other technologies is quite natural, although often unsuccessful.  Perhaps it is only instinctive that people try to blend the benefits of several different approaches into a single entity (per se).  After all, such a thing is seemingly quite rational.  More to the point, it is often believed that […]

Is there a generalized form of Six Sigma that can be applied to every organization that wants to improve their process quality?

Published:

A central aspect of six sigma is an eight-step approach for achieving dramatic improvement at different levels of the business.  The process is given by the acronym RDMAICSI – Recognize, Define, Measure, Analyze, Improve, Control, Standardize, and Integrate.  As a short cut, many just apply DMAIC. At a top management level, it functions as a […]
