A simple mapping between standards is not sufficient. This mapping can be complemented by additional descriptions. There are some delicate differences between ISO 9001:2000 and CMMI in terms of context. Therefore, the mapping must be explained by some description on the detailed difference between ISO 9001:2000 and CMMI.
Once an organization has achieved ISO registration by satisfying the necessary requirements of ISO 9001:2000, it is relatively simple to implement ISO 9004:2000 to achieve further improvements, because ISO 9004:2000 has been developed as a complementary guideline for ISO 9001:2000 and thus share similar structures with respect to assisting their application as a consistent pair.
In the same context, if there is a superset of ISO 9001:2000 and CMMI in the structure of ISO 9001:2000, it will be easy to introduce CMMI into the organization with ISO registration.
In this paper, we present an ISO 9001:2000 and CMMI integrated model constructed in ISO 9001:2000 structure, in which the interpretation of NN mapping is clearly described to eliminate confusion. Additionally, the integrated model provides an explanation of the differences between ISO 9001:2000 requirements and the practices of CMMI.
This paper is organized as follows. Section 2 briefly explains ISO 9001:2000 and CMMI. Section 3 presents an integrated model of ISO 9001:2000 and CMMI. Section 4 discusses related work and finally, Section 5 provides some conclusions.
