Systematic process improvement using ISO 9001:2000 and CMMI

6.1 Differences between the CMM ® and CMMI ® 173
activities that are performed at the project level to determine and eliminate
causes of defects. Causal analysis, however, goes beyond examining defects.
It can be applied to problems ranging from narrow project problems to
business and engineering problems that require systematic analysis and resolution.
6.1.6 Continuous CMMI ® representation: concept of threads
Maturity levels, used in CMM ® -SW for many years, indicate a preferred order
for process improvement. First, project management is stabilized. Process
variations are then minimized through the introduction of the organizational
standard process. Finally, processes are quantitatively controlled and optimized.
This order is also sanctioned in the CMMI ® and is shown in Table
6.3 [4].
