Paper Abstract:
|
Developing interactive applications according to quality criteria can be done within the environment of a methodology
centred on the user and by means of the agile but ordered realisation of its components. The analysis of functional and
non-functional requirements does not only encompass the descriptive aspects of functionality, it must also satisfy user
needs such as usability, as understood in terms of efficiency, effectiveness and satisfaction of use. At the same time, the
analysis should cover other important conditioning factors such as system reliability and security.
This article is based on the InterMod methodology whose objective is to facilitate the design of quality interactive
applications. InterMod proposes using user-centred models which allow to define the application requirements and to
describe the human-computer dialogue; both of them are embedded in an early prototype evaluation process. The
requirements models, the presentation model, and the software model are involved in this process. Several tools guide the
process described in InterMod, and here we focus on Diagram. Diagram gathers the requirements models, automatically
creates a user-friendly prototype and brings the developers and users into the process design in a continuous evaluate
phase. All the models are saved in XML allowing communication among them. Some examples made with that tool
illustrate our approach. |
