I did both in 1990-91 with the CMM and ISO - we were rated Level 2 and ISO Certified within about a month - with careful planning we had large overlap and minimal duplication. CMM vs CMMI differences are minimal (oops - hope I have not offended anyone) in so far as it is a continuous improvement model.
Not sure where your 1/10 the cost number comes from. Certainly not for the certification cost itself - in fact the external cost of ISO certification audits for a year was = or > than CMM/CMMI appraisal costs. Given that Appraisals are good for 3 years and you must recertify annually or bi-annually with ISO tips the cost the other way, even when considering internal appraisal costs.
If customer satisfaction is of no importance to your company, then yes, you do not have to measure it.
If it is important, and is a stated management business objective, then I would look for measures linked to, and supportive of, customer satisfaction. If they did not exist, then there may be issues with the measurement system related to setting objectives and measures that support them. It could be a weakness that impacts OPP/QPM, and or MA. I use the word "could" as the team would need to understand/investigate the situation. (Note: I have never had this problem in any appraisals I have been involved in as customer satisfaction has always been foremost in the companies I have worked with. Perhaps there is a selection process I use that eliminates those who do not care, or is it a market imperative that those that do not care typically do not engage in improvement and/or die?)
Anyone ever run into this in the real world rather than hypothetically?
CMMI covers much more space, and in greater detail, than ISO - thus one possible reason for the CMMI requirement. One measure of this is the relative time you imply to achieve ISO certification vs CMMI ratings. Perhaps one of the discussion group members has insight into this decision?

JErry,the CMMI MA and OPP/QPM Process areas say your measurement systems should be part of meeting customer needs and business objectives - via a somewhat long chain of logicTherefore if customer satisfaction is an important measure/objective, then it should show up in implementing and executing these process areas.This would be a rather low level criterion in making the decision on which to implementMore to the point, CMMI is a model, ISO is a standard for certification purposes, and this difference should be well understood in terms of business needs as part of the decisionEd----- Original Message -----From: jerryyzSent: Friday, July 10, 2009 8:30 AMSubject: [CMMi Process Improvement] ISO 9001:2008 vs. CMMIShould software companies pursue ISO9000 before CMMI?
ISO measures customer satisfaction while CMMI does not.
