Systematic process improvement using ISO 9001:2000 and CMMI

4.2 CMMI ® 111
from business objectives) are identified. These steps allow the most important
improvements to be identified and prioritized. Next, process action plans or
process improvement plans are developed to spell out the activities to be performed
and their associated resources, responsibilities, and authorities.
This PA also addresses the collection and deployment of actual results of
process implementation, such as measurements and work products. Use
of these ‘‘lessons learned’’ allows effective organizational learning to take
place.
Through implementation of GP 2.4, this PA addresses the need to assign
responsibility for process improvement. That responsibility is typically vested
in the management steering committee and engineering process group.
Organizational Process Definition
The purpose of organizational process definition is to establish and maintain a
usable set of organizational process assets.

Establish Tailoring Criteria and Guidelines
Establish the Organization’s Measurement Repository
Establish the Organization’s Process Asset Library
Why is this important
Use of a standard set of processes allows for consistent and predictable performance.
The OPD PA is concerned with development and deployment of those
standard processes. Whereas some organizations may generally develop the
same type of product repeatedly, others engage in a variety of businesses and
products and may need more flexibility in adapting the standard processes to
fit specific needs. Although this flexibility is needed, too much freedom may
mean that the benefits of standardization are lost. Therefore, as part of the
standard process definitions, guidance is provided on selection of life-cycle
models and the tailoring of processes and process elements.
This PA also addresses establishing and maintaining a library of process
assets and a measurement repository. This PA enables GP 3.1 and GP 3.2
across all other PAs.
