Thanks and best regards
William0September 14, 2000 at 4:00 am #65476TQM and Six Sigma are two pupils of the same school. They are similar in many ways and different in many ways. Let me elaborate on what I know (which shouldn’t take very long!).
Tools are the same. You use the same 9(?) basic tools as well as a host of statistical tests. Some may be tailored differently and a few new ones may be introduced by Six Sigma.
Methodologies are similar but Six Sigma has caught on because it is more focused on delivering what business leaders want: Numbers and profits instead of “we feel the process is much stronger now.” It was the quantification that was lacking with TQM. Although it worked in many places, the business leaders couldn’t get into it and understand the benefits clearly enough.

PS.: what are the 9 basic tools?

0October 11, 2000 at 4:00 am #65501The nine basic tools (I think) are:
FMEA
QFD
DOE
Fishbone (Cause & Effect)
Process Mapping
Pareto
Gage R&R
Control Charts
& One more I can’t remember…0October 13, 2000 at 4:00 am #65505The seven basic tools for TQM are:
1 cause and effect diagrams
2 flow charts/process flow diagrams
3 pareto charts
4 run charts
5 histograms
6 scatter diagrams
7 control chartsThere are significant differences between TQM and Six Sigma — just looking at the tools — aren’t there? It would appear that with the addition of FMEA, DOE, and others that Six Sigma is much more powerful than TQM.

AnonymousParticipant@AnonymousInclude @Anonymous in your post and this person will

I do not agree at all related to the analysis but as a reference is good.0 -
