Can anybody help me what is the diff between CMM,SEI,PCMM
and six sigma?

Answer Posted / chandru

The CMM i.e capability maturity model defines processes to
be followed at each level (by experience) to achieve the
desired result.
SEI - Software Engineering Institue that certifies the
various companies by the help of their representives in
various countries.
PCMM-Peoples CMM i.e there are about 199 people practices
followed across the various companies. i.e based on the
feed back of the people about the company,if we make
required changes that yeild better results and healthy
environment for the people working in it. ex; Black box, e-
mails,etc.
Six Sigma in brief is the standard process in moving
towards total bug free Software(ex) like 99.9999%.Though it
is similar to CMM5, it is v.rigid in some aspects like
rejecting the defect SW component and producing a new one.
No compromise in quality. Motorola company is one such Six
sigma company.
