ABSTRACT Web Portals are increasingly being used for important tasks, at a work, personal or leisure related issues. Since Web Portals provide with applications, services and information, their levels of quality are an important prerequisite for their success, and hence, a way to ensure that they do not disappear as a consequence of their not having been used. According to the ISO, there are various perspectives of quality: internal, external, and in use. Although issues related to external quality and internal quality have been widely studied in literature, we consider that it is also necessary to take account the importance of quality in use of web portals. This paper is aimed at defining a quality model to assess the level of quality in use of Web Portals. The model is founded on the ISO/IEC 25010 standard, and on some related works found in literature.

    ABSTRACT: Web applications (WebApps) and their quality specification and evaluation have been the subject of abundant research. However, the particular features of new generation WebApps pose new challenges regarding current quality models and their included characteristics and sub-characteristics. For instance, functional added value (e.g. integratedness and beneficialness), learnability in use, communicability, sense of community and, ultimately, user experience are characteristics very often neglected in quality modeling or placed appropriately in quality views. Considering the recently issued ISO 25010/25012 standards and quality models for WebApps, in this work we propose updating our previously developed quality models and framework so-called 2Q2U (Quality, Quality in use, actual Usability and User experience) in the light of those features of new generation WebApps. The resulting quality models and framework in conjunction with evaluation strategies contribute towards a flexible, integrated approach to measure and evaluate different eras of WebApps. In order to illustrate the approach a practical case for evaluating a mashup WebApp is conducted.

    ABSTRACT: This paper discusses a methodological approach to define quality models (QM) for Web applications of any kind, including Web 2.0 sites. The approach stresses the practical use of a QM, not only in requirement definition and quality assessment, but also in quality improvement processes. The primary requirement for such QMs is organization mapping, which allows those who are in charge of quality management to easily identify the actors in the organization responsible for implementing or improving each specific quality characteristic. A core QM is proposed, collecting the main common characteristics of Web applications. This is not a complete QM, but requires adaptations to cope with specific application classes, organization and project needs and practical purposes. An example of such an adaptation is given for a simple class of Web sites. The core QM is compared with ISO/IEC 25010 QMs for software products and software-intensive computer systems.

    ABSTRACT: The paper presents a practical approach to web site quality, based on a novel perspective that considers the relationships between the web site and its stakeholders. This perspective leads to identify four fundamental concepts of quality: final quality, quality in use, basic quality and internal quality. This paper focuses on quality in use, and proposes a new quality model including a well structured and balanced set of characteristics and sub-characteristics, which aim at capturing the main dimensions that impact on the quality of a web site. The distinction between actual and expected quality is then introduced and a practical assessment methodology for expected quality (EQ-EVAL) is proposed, which employs expert evaluators instead of actual users in order to make the evaluation less expensive, without sacrificing, however, accuracy and reliability. The results of the application of the methodology in the evaluation of a sample set of corporate web sites are finally discussed, showing how the model and the methodology can indeed meet the stated requirements.
