Hi Suresh, Many time discussions held in an oranization that in six sigma only those projects should be taken which need six sigma tools (Gage R&R, Cp, Cpk , DOE etc) while to maximize financial benefit thorugh six sigma various cost saving projects also taken in six sigma to spread six sigma culture and over all benefit of organization. I want to know is it correct way or should we take only those projects in six sigma which actually need complex tools. Bye Vijay Sardana
