Q. Differentiate between ISO and CMM?
Ans) The difference between CMM and ISO are as follows :-
- ISO 9000 is awarded by an international standards body. Thus, ISO 9000 certification can be quoted by an organization in official documents. Therefore, SEI CMM assessment is purely for internal use.
- SEI CMM was developed particularly for software industry and thus addresses many issues which are specific to software industry alone.
- SEI CMM goes beyond quality assurance and makes an organization to ultimately achieve Total Quality Management (TQM). In fact, ISO 9001 aims at level 3 of SEI CMM model.
- SEI CMM model gives a list of key process areas (KPAs) on which an organization at any maturity level requires to concentrate to take it from one maturity level to the next. Therefore, it gives a way for achieving gradual quality improvement.
