Measuring User’s Perception and Opinion of Software Quality

This paper presents a method for modeling users’ perception of software quality. The method aims to improve the quality of data derived from user opinion surveys and facilitate the analysis of such data. Additionally, using aspects of Belief Revision theory, the proposed model offers a way to measure users’ opinion in early stages of product release and a way of predicting the opinion subsequently formed after their opinion revisions using the initial measurements. The paper presents graphical examples from modeling users’ perception of software quality and of handling the users’ belief revision. Finally, conclusions from our case studies and data analysis are presented.
