I fully second that. Its totally baseless to assume the 1.5 sigma shift and adams theory has no grounds

Hi GB,
Apart from what robert has suggested please check your Measurement system. Have you done Gage R&R/bias/accuracy/linearity/stability whichever is applicable. I feel there could ba a Gage issue somewhere in your measurement.

Hi
Once you have decided to transform the data after thoughroughly undrestanding your process characteristics(assuming there is no other way of getting the normal distUse a Lambda of -0.5 as it gives you a better transform into a Normal dist(see below) I have used Minitab14 to get this

Not every six sigma tool may be of high value in construction. (I can’t see a DOE, for example.) But the philosophy and some of the tools can be brought into play.
A couple years ago, I interviewed for a six sigma position with Neumann Home Builders in Illinois. They wanted somebody to plan their processes for getting people into their new…[Read more]

To me, Six Sigma is a philosophy and a set of tools that can be used in a variety of functional areas to address waste.
Supply Chain Management (SCM) is a function. (And it can be a very tough function! Suppliers can be very tough to work with.) Six Sigma can be used in SCM, just like it can be used so many places.
 

They have done two projects already and are in the process of taking up more. One of the was on efficiency improvement & a subprocess optimization

Arun,
Your question is a bit broad.  Immediate answer is to gain support for SixSigma from the leadership.  But I’m not sure if youcurrently have responsibilty for SixSigma or if you knowing the benefits of it simply have the view that it can help to improve the business.  Please be  bit more specific so that the advice can be of merit to help you.

On eyear or three years, depends on how your company wants to make the determination. My comapny uses one year savings in all aspects.

A good question indeed. There is no harm in going from 6 to 7 og 8. In fact airline industry operate at 10 or more for flight take off & landing, but for all practical purposses in an industry where humal life is not at risk six sigma is a good enough improvement benchmark.
More than that may not be worth the Time, money$$ and effort.

Hello Atul,
Cpk = Min[(Avg.-LSL)/ 3 Std.Dev.,(USL – Avg.)/ 3 Std.Dev
Since your Target(nominal) is 15.45mm & LSL is 15.30mm here you have a one sided spec. Hence you have to use Cpk = (Avg.-LSL)/ 3 Std.Dev. Here the avg. is the mean of your data.
Hope this helps

In much the same way as it is done at other places. Start with a problem statement and apply DMAIC methodology to attack the problem.
let me know for further help.
Regards

Std. dev.=SE Mean/sq.root(number of samples)

Hi!Kavita,
You have not made it clear weather you as an organisation is new to six Sigma or not. Anyway assuming that you people are new to it.
There are a lot of ways in which you can use it in HR. Basically Six Sigma can be applied anywhere where there is a process(in your case transactional) or product to improve an existing process(DMAIC)…[Read more]
