Measurement and quantification of quality characteristics in quality-in-use

Abstract

Quality-in-use model which is one of software engineering quality standard series (SQuaRE) has been revised in 2023. As a result of this, ISO/IEC 25022 which described about the measurement of quality in use also be required to revise. As the concept of this standard is to deal with influence on stakeholder by use of product, system and service in specified context of use as quality, the target stakeholders were wider. According to this change, measurement methods for “Beneficialness” and “Acceptability” which are new quality characteristics and “usability” which is one of the sub-characteristics in “Beneficialness” are also required. This paper shows the new concept for measuring these quality characteristics, especially “Beneficialness”. "Beneficialness" is structured by "usability", "accessibility" and "suitability" as quality sub-characteristics. , By representing these sub-characteristics as measures of quantitatively, new quality models can be measured.
