QUALITY ENGINEERING ANALYSIS FOR HUMAN FACTORS AFFECTING SOFTWARE RELIABILITY IN THE DESIGN REVIEW PROCESS WITH CLASSIFICATION OF DETECTED FAULTS

摘要

Software faults introduced by human development work have great influence on the quality and reliability of a final software product. The design-review work can improve the final quality of a software product by reviewing the design-specifications, and by detecting and correcting a lot of design faults. In this paper, we conduct an experiment to clarify human factors and their interactions affecting software reliability by assuming a model of human factors which consist of inhabitors and inducers. Finally, extracting the significant human factors by using the quality engineering approach based on the orthogonal array L_(18)(2~1 x 3~7) and the signal-to-noise ratio, we discuss the relationships among them and the classification of detected faults, i.e., descriptive-design and symbolic-design ones, in the design-review process.
