Re: Differance between CMM level 5, ISO and six Sigma certification.
There is no hierachy between ISO and CMM because-
"although an ISO 9001-compliant organization would not
necessarily satisfy all of the level 2 key process areas, it would satisfy most of the
level 2 goals and many of the level 3 goals. Because there are practices in the
CMM that are not addressed in ISO 9000, it is possible for a level 1 organization
to receive ISO 9001 registration; similarly, there are areas addressed by ISO 9001
that are not addressed in the CMM. A level 3 organization would have little
difficulty in obtaining ISO 9001 certification, and a level 2 organization would have
significant advantages in obtaining certification."
