Instantiating Web Quality Models in a Purposeful Way

摘要

Web applications and their quality evaluation has been the subject of abundant research. However, models have been used mostly for the purpose of understanding, rather than improving. In this work, we propose utilizing a quality modeling framework to instantiate quality models with the specific purpose to not only to understand the current situation of an entity, but also to improve it. Our approach instantiates models for both external quality and quality in use, resulting in a requirements tree for both followed by evaluation and then combined with a mechanism to develop relationships between them. Hence, improving is driven by understanding these relationships, namely, 'depends on', and 'influences' in alignment with the ISO 25010 quality life cycle model. This is illustrated with a case study showing the underlying strategy from model instantiation to application improvement.
