Good reference book,
Verified Purchase(What is this?)
This review is from: What Is Six Sigma? (Kindle Edition)
I would have given this 5 but when getting the electronic version on a kindle app on my Ipad the page numbers are not visible. The more detailed index at the back doesnt show the page numbers either which is really annoying and makes this index useless. If you are getting this for your Ipad on the kindle app then think about getting the paper version instead.
