Agile Development of Interactive Software by means of User Objectives

Agile methods, model-driven developments and user-centred design are three approaches widely accepted in the development of interactive software. In this paper we present InterMod, a new approach that integrates all three methods. The project planning is based on User Objectives and the process is organised as a series of iterations, where the work is distributed in different workgroups according to some developmental and integration activities, each one driven by models. The requirements are incrementally collected and evaluated with models based on user-centered design. To speed up this validation, we put forward the SE-HCI model, which enriches a human-computer interaction model with the semantics of the application and some basic characteristics of an abstract prototype. This allows gather and validate the requirements incrementally. Moreover, this iterative process speeds up the development and generates results from the
