Upper management is behind it.  And we are 90% committed to signing up with Othros Lean program.   We even have a team that will train with Ortho picked out.   Having upper management behind wont ease the minds of those opposed.  Are there any companies that experienced lower morale levels to go with the higher efficeincy numbers?  I assume initia…[Read more]

Hi Thibaut Martin,
I am working in France with a group of consultants, we are associates of Valeocon, international six sigma company. Since 1995 we have accumulated strong six sigma operationnal experience in industry and financial services and we are currently deploying it in large international French companies. I would be more than happy to…[Read more]

WOW!  27 Green Belts in three years is a lot of work for that single Black Belt.  I would think that 27 Green Belts is too many for one Black Belt to train and mentor by his/herself in three years.  It also appears to be too large a number for that same Black Belt to continue to mentor as they work in the process.  27 is trainable, but too man…[Read more]

Thanks all for your reply.

All in all, its amazing. I can’t believe how much variation we humans ourselves have. Just look at the many different answers for such a simple question.6 sigma is a target (defects of 3.4 ppm) which we all aim for. I agree  not many have achieved that. However, the underlying concept of 6 sigma is to strive for Continuous Improvement. We start o…[Read more]

Hi, it has been very interesting reading all the comments.
I have a question regarding Normality Tests using Minitab.
I notice that when we conduct Normality test in Minitab, we do not specify an alpha value for the 3 tests in Minitab (Anderson-Darling, Shapiro-Wilk & Kolgomorov-Smirnov).
Therefore, how do we decide whether the data is…[Read more]

Ben,
Great job with the Components Search! It’s exciting when you know you’ve found the number 1 problem (the Red X) and not some tiny, 10% issue that someone’s theory might have offered up. Keep going!
Best,
Marc

In MINITAB DOE, sample size means either replicates or adding center points.
You can only do it for 2 Level factorials Design or Plackett-Burman Designs.
Good Luck.
 

Vidyut,
Thanks for your response. I am very excited to hear about the outstanding results you got by taking the Shainin approach. I’ve had the same kind of experience on many high profile projects in which there were high defect and warranty rates, where design engineers tinkered with the problem for years (literally), and then they give up a…[Read more]

All –
I would recommend to those who would like a better understanding of the power of the Shainin techniques (which is specifically to identify the Red X when it is an interaction) that they read Keki Bhote’s World Class Quality, 2nd ed. The Shainin philosophy states that most of what causes variation are interactions and something you would le…[Read more]

Hi, though it is non-normal, we can transform the data to a Weibull distribution right?

The things that make a project complete are no different for a Green Belt than thya are for a Black Belt.  It is a matter of attaining the goals set forth in the project object, proving that the gains achieved are sustainable, and developing a control plan that captures the sustainment methodology.
These elements must then be approved by the…[Read more]

Search the forum using key word “hotel” and you’ll find some interesting information which may help you.
Cheers.

If for example a gage has GRR of 10% and I use it measure a part of height 10mm. The gage gives a reading of 10.09mm. Since the tolerance of the part is 10+/-0.1mm, I accept the part. Is there any risk associated with accepting the part since it is marginally passing the inspection tolerance? As against a gage with 20% GRR, is the risk of…[Read more]

The idea that a Black Bet is the powerhouse for delivering savings is directly on target, but teaching is a major part of that delivery. A MBB should be able to training people at all levels of the organization in Six Sigma. An experienced BB needs to spend some time teaching/co-teaching Green Belts and other Black Belts. Black Belts will gain…[Read more]

I have never heard of this before. Sorry.

Ask them for examples of where their Six Sigma deployements failed or failed to meet the customer’s expectations. Call those customers and verify their story. If they have none, it’s a crock :)!
Keep us posted. I’d love to hear how your evaluation is progressing.

David,
I suggest putting together a specification and submitting it to those companies that you feel deserve to bid on it. Select the companies from the list found at http://www.isixsigma.com/co/six_sigma/. See how willing the companies are to put together a quote for you — that will tell you something. Look at their past experience. Ask for…[Read more]

Adding to that, if the variation is more significant within subgroup, we can use a X-bar R or S chart to monitor within subgroup variations. If the variation is more significant between subgroups, we can use X-bar MR charts.

Thanks, got it. I’ll have to check the accuracy for any bias before looking at the risk.
