Abstract :
Different concepts of software quality are reviewed and discussed in this paper. Based on this, a hierarchical model of information system (IS) quality concepts developed in the research project SOLE is presented. This model aims at a division of quality concepts consistent with the different decision makers and decisions made during the software life-cycle. The main division is into IS cost effectiveness, IS use quality and IS work quality. The last two are further divided into requirement quality, interface quality, and efficient IS management, evolution quality and operation quality, respectively
