Information systems development is a very important activity that is performed continuously in Information Systems departments. We can say that quality is a complex measurement of a product or service that people demands. However, quality is a measurement that is composed by a set of aspects. Quality measurement can be performed in concrete or abstract form. Software quality is a very important issue that developers must address properly, but a lot has to do with abstract aspects of it nonetheless. We proposed an approach that could reduce the abstractness of software quality measurement. In order to prove it, we conducted a study with encouraging results. We found that end-user participation in the evaluation IS quality can be improved.
