A Framework for Early Usability Integration in Web Applications Development Process

Abstract

Developing usable products becomes more and more important for software developers. Developing web applications it’s more challenging than developing desktop applications due to the various users that will interact with the final product. Satisfying users’ expectations becomes a very difficult task, as usability proves to be a very complex goal to achieve in the context of increased productivity targets in software engineering process. The present chapter focuses on the idea of rethinking the concept of usability moving from the traditional view of usability expressed in the internal characteristics of the product towards usability understood as deriving from the quality of interactions between humans, their work and the web design product. Usability is not only an add-on or a final result in the design process but it is embedded as a main concern within the design process itself. In order to build usable products, a great attention should be oriented to users and their needs, and this can be a very challenging task for software developer teams. In this chapter we will describe an interdisciplinary approach, based on applying social sciences techniques and methods that can be helpful in overcoming the difficulties in understanding the users. We will provide a short description of the proposed methods, a guide in applying these methods and a framework that integrates each of the proposed methods into the corresponding step of the web product development life cycle. The chapter ends with the presentation of two case studies showing the applicability of the proposed solution in real design contexts.
