Critical view of the application of the ISO standard for quality assurance

Abstract. The aim of this paper is to initiate a debate on quality assurance and the application of the ISO 9001 in the system development field. It is claimed that unquestioning application of ISO 9001 can be a backwards step in the practice and research of system development. Five aspects of quality are identified in order to design and evaluate the quality of information systems: technical quality, use quality, aesthetic quality, symbolic quality and organizational quality. We find that the standard solely emphasizes technical quality. The standard promotes the ideal of linear, phase-oriented system development, based on a fixed requirement specification and a document-driven process. This is in contrast to most research findings, which criticize one-sided adaptation of phase orientation in system development.     

PROCESSUS – Integration of SEI CMM and ISO quality models

Integration of the two best-known quality management models for software production and maintenance, the Capability Maturity Model and the ISO 9001 Model (including ISO 9000-3) is of great interest for both the European and the American software market. The definition of a quality management model which would conform to the requirements of both models and use the advantages of each was a key goal of our research work within the project PROCESSUS.1 Research work was conducted in two steps: first, the detailed comparison of both models was made in order to define their common issues and specifics of each model, and secondly, the integrated model based on the results of the comparison was defined. In this paper the comparison method and results are described. Further, a method for the integration and a framework of the integrated model are presented. The core of our work is actually the content of the integrated model. Due to extensive content of the integrated model examples of some parts only are given in the appendix. The integrated model presented in this paper has already been successfully used in organizations which are cooperating in the project PROCESSUS o these organizations achieved the needed maturity for certification to the ISO 9001 standard and a maturity level near level 3 of CMM.
