Neeraj:
You certainly need to start with identification of business performance drivers. These drivers are key measures of the business performance. Then look into reducing waste using Six Sigma or Lean principles. This will focus on the bottom line. In addition to reducing waste, you may look into expanding services innovatively.
With these…[Read more]

Fred:
You sound like a very smart guy. Are you suggesting something to improve Six Sigma?

Hi Neal – yes this is helpful thanks.
I guess the main point that I am arguing for is that if a business is executing FMEAs as part of its Quality Mgt system, then it should be documented.
Thanks
Paul

The Six Sigma Business Scorecard includes a process for calculating corporate sigma level by calculating an overall performance index, used as the yield for the corporation. – Paul

I believe August 05 issue of the Six Sigma Forum magazine was devoted to innovation.

EdG: Thanks for sharing these three points of TPS, Thinking Production System. But, when you reduce the thinking from this TPS, what is left, Lean Thinking, or the Lean System, one without thinking, just doing.
That’s why TPS discourage layoffs, while with Lean Thinking, layoffs is the first expectation.

A negative cpk in terms of goal posts means that you missed the extra point (provided that you had previously scored a touchdown) or that you missed the field goal (you’ll have to kick from a shorter range).

There is a book titile Six Sigma Business Scorecard. You may look into it.

Mr. Bender wrote a SAE paper in the 1960’s about doing a statistical stack calculation to determine the expected overall dimension for sets of individual dimensional tolerances occurring in a linear path. His recommendation basically was to multiply the square root of the sum of the squared tolerance values by 1.5. Hence when a linear tolerance…[Read more]

No you cannot figure MMC bonus tolerance with runout.
Runout tolerances are always a constant values limiting the variation that a surface revolving about an axis causes a test indicator vary.  

Bill:
P value alone does not determine strength of the correlation. What is the r-sq. value, or the correlation coefficient? If that is small, it implies there is no correlation with 95% confidence.
Paul

You may checkout Th Six Sigma Performance Handbook for reasons of failures. It lists various types of failures.
Good luck!

Geometric tolerances i.e. Ø9.4-8.9 |⊕|Ø0.36Ⓜ|A|B|C| have a variable upper specification limit. That limit can be visualized by making a histogram with both distributions on the same graph, the one for the geometric tolerance and the one for feature size.  The scale of the graph begins at 0 and at the geometric tolerance’s specified USL the size li…[Read more]

Mike:
I agree with you about inclusion of seven and many so called TQM tools in the Six Sigma tool box. By saying ‘beyond TQM’ did not mean to exclude TQM, I meant Six Sigma was built upon previously known tools. I hope it clarifies it.
Thanks for your comments,
Paul

Yes, the improvement initiative must become a culture. They require passionate hardwork in applying proven tools creatively, and a very direct and disciplined leader. One can either make a choice of copying somebody else’s successful practice, or learn from the successful practice and adapt to ones organization. We are too much tuned into…[Read more]

We lost track of “Six Sigma/TQM- Which is Better?”
The challenge with TQM was that it was poorly defined, meant different things to different people, and results were promised after three years, which was about the average stay of the Quality Manager on the job. People got tired of trying TQM, which eventually became a Total Quality Mess.
Six…[Read more]

Use Minitab –  good product!

Yes, Trev honey, it’s me.

I believe everyone involved in Six Sigma is responsible for its downfall from CEO, trainers, consultants, Champions, and Practitioners. We all jump onto something like Six Sigma and start applying in rote manner. We need to look at each project, decide what’s the efficient approach, and apply necessary tools to get desired results.
Most important…[Read more]

You are good at writing ‘nonsense’.! Anything better?
