Abstract

Usually, the process of development of services available as web applications considers only functional requirements. Since, an evergrowing number of users take advantage of different kinds of communication channels and devices, this process must be revised by considering new aspects: quality of service (QoS), user profiles and technical characteristics of channels. In previous works, we proposed a methodology that provides a rational to formalize the redesign process of existing services to support multi-channel access. This paper extends our approach and highlights how the QoS dimensions can be considered quantitatively in the different phases of the methodology. Moreover, an hybrid approach that allows the QoS evaluation, during the development of a service, is proposed.
