i did not rebel too much. i went along with the program. it is so Dilbertian. in the 90's it was ISO-9001, in the 00's it was 6-Sigma. i have seen a grand total of one engineering problem that was solved by proper use of statistics - and that was before 6 Sigma. i think for many companies, it is seen as a marketing thing. then they can put it in their ads, "ISO-9001 certified".
