Me too! [email protected]0March 17, 2005 at 11:32 am #116464
I am actually taking an SPC class currently. My professor seems to like to use M&Ms to do different experiments in class.
For example… Using M&Ms for attribute control charts. He gave every student a bag of M&Ms and he asked us to open the bag and count the different colors of M&Ms that we had. He would be around the room and ask everyone what color we pulled out, and whether or not it was a defect (for example if it had the M stamped on correctly, or if there were 2 peanuts in the M&M, etc.) We would then wait a couple of minutes and then take our next sample. And so on… We charted this as we went.
The only thing that confused a few people was that we only did one chart and plotted our control limits on the first graph. As long as you fully explain that this is not the way to do it in industry, then you should be allright. It worked really well. took about an hour to go through the whole exercise, plus we got a free bag of M&Ms. Everyone was pleased and learned first hand how to apply some SPC tools.0November 15, 2004 at 11:44 am #110786
Oh ok Dog Sxxt
yeah… thanks for the advise, but if you find an MSA book with %p/t let me know. I haven’t been able to find that in any book.0February 26, 2004 at 9:54 pm #96121
Yes. Do a tally on the numbers. Find out what’s the high percentage numbers, then play. Also, analyze the data to see if there are any trends or patterns that happen.
Good Luck!0February 10, 2004 at 8:29 pm #95284November 15, 2003 at 10:34 pm #92563
Has anyone got any reply so far on this question??
I can see that the thread is more than an year old?

I am a mechanical engineer who’s applied DFSS in the design and development of gas turbines (low/medium duty). I can understand your concern for creativity and innovation if we were to limit these to the Customer’s vision.
However, I would look at it from a different perspective to realize than in fact VOC does not imply limited innovation.
First of all, from a personal point of view and sentiments, as an engineer I find it very challenging designing by constraints. While most people find this to limit creativity, I believe that it requires a particular ability to find “unusual” non-standard solutions under the most challenging conditions. If this is not the best example of creativity I do not know what is !
Secondly, one often realizes that the Customer does not always know what it needed/wanted until someone makes evident the need. If you design and develop around the Customer’s “top” CTQ’s (i.e. the very general, high-level requirements/needs) you still have the freedom to introduce innovative solutions that the Customer might have not even considered as an alternative to the more obvious ones. Of course, the more detailed and specific is the the Customer’s CTQ, the more limited will be the innovation. But the point is that you can always begin at the top level (the very basic and “primtive” need) to then let your creativity lead to a new solution.
…these are just my thoughts on the subject.
