ソフトウェア設計中の直交表導入による開発効率の効果と課題

抄録

The orthogonal arrays used to evaluate software are large because they are used for in-circuit tests after the software design phase. These evaluations take much time, and it is difficult to make exhaustive checks of the detailed specifications. Methods using small orthogonal arrays in the design process have been proposed and implemented, but because of a lack of understanding by designers and leaders, they have not been introduced into the design stage and fault detection has not been carried out during the design stage. The use of orthogonal arrays for software evaluation has taken hold, however, and it has been successfull in reducing defects. Practical proposals for introducing orthogonal arrays into the design process, and the challenges faced, are discussed in this report.
