ソフトウェア開発における設計過程への品質工学的手法の導入

抄録

Integrated software debugging methods using orthogonal arrays have become an in-house standard that is frequently applied, but the applications have been limited to the later stages of the design process, so a study was undertaken with the object of application to the entire software design process during in-house software development. The study began with the in-house standardization of the integrated debugging methodology, which was then applied to unit debugging using small orthogonal arrays, and applications were then expanded to include checking methods during the design process, working from down-stream to upstream in the design flow. The design flow was also reconsidered,the checking system and the points at which it was to be applied were studied,and improvements were implemented. Finally, the application of parameter design to software design was studied and a proposal was made. The generic function of software was defined as stable functioning and operation with a variety of settings in a variety of usage environments. After sigrial factors were assigned to an orthogonal array and debugging personnel were assigned as noise factors, debugging was carried out and the bugs that were found were evaluated. The following is an in-house case study report, including the results of a study of the effects obtained and further issues.
