Six Sigma
Hi, 
My name is Josh Maxton. I am a junior Industrial Engineering student at Wichita State University. My courses this semester just started talking about Six Sigma, and it sparked my interest. I am a beginner, so my knowledge is limited. I would greatly appreciate any references to resources or anything that will help me improve my understanding of Six Sigma, for both my courses and my personal interest.

Thanks,
Josh Maxton

Hi Josh,

The gist of the Six Sigma thing is that in Lean Metrics you want to, instead of measuring wages against production, measure customer satisfaction against number of defects, so by attacking processes using DMAIC (define, measure, analyze, improve, control) you can reduces your SIPOC time (supplier, input, process, output, customer) with the end goal being bring part defects below 3.4 in a million.

Keep in mind a part may have many opportunities for defects, this means if 100,000 parts have 10 things that can go wrong with them, then that is a million potential issues per 100,000 parts.  Sigma is your current number of mistakes per million opportunities over x number of parts.  Once you have calculated your current sigma for a given process, in the measurement phase of DMAIC, then you can look for ways to lower it, if needed.

That's all i know so far, and that is what I learned here in Tooling U-SME.


Hope this helps
