A couple of years old but still a good read.
There are excellent articles on lean and six sigma at http://www.1stcourses.com/articles-details.html
The lean six sigma toolbook is also an excellent book. I believe it was written by the George group.
There are several good articles on <a href="www.villanovau.com/.../">lean six sigma available</a>.
Lockheed Martin does a lot with six sigma, good read. Thanks.
Nothing as good as Six Sigma Certification try it & u will know
