Six Sigma and Fishbone Diagram
Thanks a lot for informing that, would you explain me more about DMAIC road map in order to understand that relation.

Fishbone Diagram for Brainstorming and Collecting Input
I have made extensive use of the fish bone diagram in lean sigma project in order to gather brainstorm input regarding all potential influencers of the outcome. In the y = f(x) methodology, the xs are the many components that influence the outcome of the process - Y.
The key to the Six Sigma and Lean DMAIC approach is not to presume that something is significant or insignificant until you can back it up statistically. Sometimes the outcome is not what you expected!
The fish bone method allows us to collect many potential xs. Then before using the statistical tools, filter your big list of xs with an an FMEA analysis and reduce the number to perhaps 10 or so, before analyzing further.
