Une nouvelle perspective pour gerer le soutien de l'utilisabilite dans l'architecture logicielle.

摘要

Over the years it is noticed that besides an increasing focus on quality attributes, increasing attention is being paid to the architecture of a software system. And within the software engineering community, it is commonly accepted that the quality attributes of a system such as performance or security are to a large extent, constrained by its architecture. Is this constraint also true for usability?;We propose a usability driven adaptation of the quality attribute workshop (QAW) to assist software development organizations in discovering and documenting those usability requirements. An empirical experiment, conducted to assess the utility of this method, reveals that participants were successful in identifying the architecturally relevant usability requirements. It also helped discern the usability aspects that would not have been necessarily defined if this technique had not been employed. We show how this method could be integrated within an existing architecture-centric software development process. (Abstract shortened by UMI.).;We present a case study that consists in adapting an existing software architecture analysis method (SAAM) for the purpose of deriving the interdependencies between architectural characteristics and usability requirements. More specifically, we investigate the impact of implementing usability requirement changes on the architecture.
