یک مدل واحد و یکپارچه برای پیاده سازی ایزو 9001:2000 و CMMI توسط سازمان گواهی ISO-

ISO 9001 is a standard for quality management systems and CMMI is a model for process improvement. If an ISO-certified organization wishes to improve its processes continuously, implementing CMMI would be a good choice, as it provides more detailed practices for process improvement than the ISO standards. However, there are two issues that need to be resolved when an ISO-certified organization implements CMMI. First, it is not easy to identify any reusable parts of the ISO standards, and it would be advantageous to be able to reuse selected portions of the ISO standards during CMMI adoption in order to use existing resources to their best advantage. Second, it is difficult for an ISO-certified organization to implement CMMI in a straightforward, easy manner because of the differences in the language, structure, and details of the two sets of documents. In this paper, we present our unified model for ISO 9001:2000 and CMMI that resolves these two issues. Our model would be an extremely useful tool for ISO-certified organizations that plan to implement CMMI.

ISO 9001:2000 requires that an organization’s processes undergo continuous improvement even after ISO certification has been achieved. CMMI provides an organization with a means to accomplish further process improvement. CMMI is a very detailed set of documents that contain many more of the basic concepts for process improvement than can be found in ISO 9001:2000. In the past, several ISO 9001:2000-certified organizations have attempted to embrace CMMI concepts by implementing SW-CMM, which is only one part of the CMMI set of documents (Mutafelija and Stromberg, 2003b and Paulk et al., 1995). To implement CMMI in an ISO-certified organization efficiently and effectively, both the common and different parts of the ISO standards and CMMI documents must be identified. ISO 9001:2000 requirements can be mapped to CMMI practices (Mutafelija and Stromberg, 2003a and Mutafelija and Stromberg, 2003b). However, the following limits have been identified in this mapping process. First, a requirement of ISO 9001:2000 can be mapped to many CMMI practices. Conversely, a CMMI practice can be mapped to many ISO 9001:2000 requirements. These mappings are useful for comparing these two frameworks, but they may cause confusion during the decision-making process. Second, it is difficult for organizations to understand and apply these mappings during CMMI implementation because they only describe the degree of the correlation between ISO and CMMI without providing any explanation of these mappings. Third, the mappings do not describe CMMI from an ISO viewpoint. The structure and words that are used by CMMI are not familiar to ISO-certified organizations, which makes it more complicated for an ISO-certified organization to implement CMMI. This paper proposes a model in which the contents of ISO and CMMI are unified. Our unified model provides a solution that allows us to deal with the limitations noted above. The remainder of this paper is organized as follows: Section 2 gives a brief explanation of ISO 9001:2000 and CMMI. Section 3 discusses related works. Section 4 presents our unified model of ISO 9001:2000 and CMMI. Section 5 compares our model with related works. Finally, Section 6 provides our conclusions.

This paper has presented our unified model of ISO 9001:2000 and CMMI. Our model has the potential to help ISO-certified organizations implement CMMI. Our model describes the correspondence that exists between CMMI and ISO 9001:2000, which can be useful in the decision-making process. Furthermore, it gives explanations to help elucidate the application of our model in the implementation of CMMI by an ISO-certified organization. It also uses a structure that is familiar to ISO-certified organizations. It assists organizations to perform the necessary gap analysis and to maintain their quality documentation without any further difficulty when they adopt CMMI. Finally, an organization will be able to implement ISO 9001:2000 and CMMI simultaneously by applying our model, even if the organization does not have an ISO certification. In the future, we will evaluate this model empirically to confirm its efficiency in the implementation process.
