Hi, I have just gone through a white belt training for the very basic overview about six sigma. I read the above topics, and found them very useful. I just want to know about various six sigma tools available (like Gage R&R, Cp, Cpk , DOE). Actually these short forms are not very much helpful, can you please ellaborate on these (means what is Cp, Cpk, and DOE). I have a little bit of idea about Gage R&R, but nothing about the rest. If you could add some more to these, it will really be helpful. Regards, Amit
