Rhetorically speaking, what is the purpose of ISO9000?  Is it a standard of expectation, much like Six Sigma?  If an organization is currently performing to a Six Sigma level, would there even be a need for this standard?  If this standard was perfectly deployed and implemented in a corporation, would it be a Six Sigma company?  Do you think Six Sigma should be apart of ISO9000, or should it be the other way around?  Is there any statistical evidence of a correlation between ISO9000 and business performance?  Is it possible for a 4 sigma organization to be ISO9000 certified?  What about a 3 sigma company, could it be ISO9000 certified?  Where is the threshold, if any?  It almost seems that you have a “subordinate” perspective of Six Sigma.  What would happen if you turned this perspective upside-down?
