Abstract
To execute a quality measurement in a system development process, we have been traditionally depended on the quantitative metrics, such as a number of errors suggested at reviews, a density of the checklist used and defects extracted at tests. Since April 2007, we have aimed to develop a qualitative factor for the quality assessment by focusing on the quality characteristics shown in JIS X0129-1. As a result, we have succeeded to draw up a systematic diagram of quality characteristics, and achieved to develop the new assessment tool based on not only quantitative metrics but also on a qualitative perspective. From now on, we will examine in detail of our new method of quality assessment, and use it practically for measuring the quality of designs, and programs.
