CMMI Appraisal
There is no certification in CMMI but appraisal. An organization can have a
capability level or maturity level rating. Most organizations value the
measurement of their progress through appraisal.
Appraisal can occur because the organization wants to compare its processes
with CMMI best practices. The organization also wants to know in what areas it
can improve. An appraisal is also a way to tell the organization’s suppliers and
customers that its processes are at par with CMMI best practices. It is also a way
to meet the requirements of customers.
Appraisals are of three classes, depending on the organization’s improvement
opportunities and its comparison with the CMMI best practices. A Class A
appraisal is a formal appraisal that can provide a level rating to an organization.
The appraisal teams use an appraisal method and CMMI model to evaluate the
organization. When the results are out, the organization can then plan its
improvements.

CMMI Applications
According to Software Engineering Institute, an appraised organization
experiences increases of performance in customer satisfaction, quality,
productivity, schedule, and cost. The median increase varies from 14% for
customer satisfaction to 62% for productivity. The CMMI model deals with the
“what” instead of the “how” so it cannot guarantee increase in performance for
all organizations.
