Quality, Quality in Use, Actual Usability and User Experience as Key Drivers for Web Application Evaluation

Due to the increasing interest in Web quality, usability and user experience, quality models and frameworks have become a prominent research area as a first step in evaluating them. The ISO 25010/25012 standards were recently issued which specify and evaluate software and data quality requirements. In this work we propose extending the ISO 25010 standard to incorporate new characteristics and concepts into a flexible modeling framework. Particularly, we focus on including information quality, and learnability in use characteristics, and actual usability and user experience concepts into the modeling framework. The resulting models and framework contribute towards a flexible, integrated approach to evaluate Web applications. The operability and particularly the learnability of a real Web application are evaluated using the framework.
