Uma linguagem visual para descrição de use cases

Abstract

In order to success during the development of a software project, it is necessary to know its requirement, whether they are functional requirements or non-function requirements (quality attributes). In that direction, the use cases have been widely adopted by both Software Engineering and Human-Computer Interaction professionals. However, its fragmented and textual form of the system description has not been enough to provide interest concerned to the user interface design. This fact has led human-computer interaction professionals to create their own methods and techniques which often go in the opposite the philosophy used by software engineers for modeling the user-system interaction. Therefore, aiming to improve the support to use case description integrated with the user centered-design, it is proposed the Visual Language for Use Case Description - VL4UCD. In this work, it is defended the use of VL4UCD during the tasks of analysis and requirement validation, of form to address, still in the initial project phase, the concerns of both groups (software engineering and human-computer interaction) about of software interactive system development.
