Systematic process improvement using ISO 9001:2000 and CMMI

7.4 Third phase: Establishing 211
poll of process improvement practitioners shows that most would rather
implement both standards at the same time if given the option. Concurrent
implementation is more efficient because both models have similar concepts
and have based their requirements for developing and managing product
development on the best industry practices.
To prepare ourselves to use the ISO–CMMI ® synergy, we first have to
understand the major similarities and differences between the CMM ® and
the CMMI ® , as described in Chapter 5, and consider the steps required to
transition from one to the other, as shown in Chapter 6.
7.4.2 Potential transition cases
Chapter 6 discussed the transition from the CMM ® to the CMMI ® and from
ISO 9001:1994 to ISO 9001:2000. This chapter explores using the ISO–
CMMI ® synergy not only to transition but also to create more robust processes,
while attaining ISO registration, a CMMI ® rating, or both.
We described several frameworks in Chapters 3 and 4 that can be used
for process improvement. Here we consider how process improvement experience
can be advantageous when using the ISO–CMMI ® synergy. Table 7.1
indicates some possible cases for organizations that have decided to register
with ISO 9001:2000 and attain a specific CMMI ® maturity level. Transition
approaches for these cases are described in detail in the following sections.
To preserve their certification, most ISO 9001:1994 registered organizations
will have to transition to the new ISO standard. Similarly, many organizations
have reached some CMM ® maturity level and wish to transition to
the CMMI ® . Many organizations are both ISO 9001:1994 registered and have
attained some CMM ® maturity level. Because the sunset for both standards
is at the end of 2003, those organizations will have to address the changes
in both standards and develop transition strategies.
