i have the baseline data reflecting 23% difference in pre and post review defects.
Also, if you can guide about he typical steps to follow as six sigma projects for the same, it will be great help
thanks guys for your reply,
I know that you all emphasised on need ofhaving knowledge of crystal ball. What all resourses I can see upon for the same.
Also, I would like few examples of situations where crystal ball can be aptly used….
Thanks in advance
The reason that there’s so much store in the numbers is that it gives the managers something to use to manage the business that removes any interpretation. For a large business this is crucial – the org is managed by internal team benchmarking.If you can get the right metrics in place this works very well indeed. The challenge is to continuously…[Read more]
Thanks, Andy. I now feel like I’m not necessarily barking up the wrong tree.What’s the answer to your questions?I’m more interested in the approach to:
– working out a relevant fudge factor for a particular process domain (I doubt that’s corporate specific, more likely business process type).
– understanding the benefit/cost of continuous…[Read more]
of course they’ll move (usually becoming worse as they aren’t being watched). That’s the nature of any time series data. But, as you say, the shift varies from case to case.So why hard code in 1.5 sd into the conversion tables and obfuscate the situation?Surely this just makes it harder to understand how the tools and techniques work as there’s a…[Read more]
thanks for the responses. I know what the data mean. I’m not familiar with six sigma, but I used to build mathematical and statistical models of various types of processes (inc. chemical reactions, physical systems, and manufacturing processes).I found it very odd that a discipline that’s focused on understanding the quality of the data that it…[Read more]
ppm vs dpmo is a smokescreen, the point is that you cannot simply rollup the metrics to get a sensible number as you’ve no view on the significance of each process to the overall defect rate for the end customer. So the suggestion is that you measure that defect rate directly.
Excellent suggestions, Sue. These are helpful for anyone looking at on-line training. Sometimes it’s difficult to be a shopper for eLearning because it’s not an area we have experience with. These are questions every buyer should ask of the provider.

David – search for “Blended” and like training terms in the forum. Here’s a link to one of the discussions: http://www.isixsigma.com/forum/showmessage.asp?messageID=87316. I know Doug personally, and I recommend you contact him directly. He has a great deal of experience and research (both his own and others) at his disposal. Although…[Read more]
Hi David – could you describe with more specificity what you do currently during weeks 1 and 2? E.g., do the students receive part of the curriculum during week 1 and the balance in week 2? What happens in the classroom? Lecture or activity?
Interesting exchange. I’m consistently amazed at the how individuals who supposedly make decisions on the basis of data will express opinions here based on a sample size of one.
Ron – I would encourage you to read department of defense data and analysis on the effectiveness of self-directed on-line training and reconsider your opinion.
O.K. – I can accept that. I suppose my assumption was that there was control charting all along, not that there’s just data that is now being charted and special causes assigned. Thanks.
Perhaps an equally silly question – does it really matter? If you’re looking at process capability based on a year’s worth of data, does the inclusion or exclusion of the relatively few data points change the respective values?
