The best practices of software engineering indicate that the verification activity is essential to achieve some quality during the software construction. In UML-based development processes, one of its main focuses is the detection of inconsistencies in diagrams that represent the software. However, most of these processes, such as Iconix, apply only informal techniques (eg. visual model inspections), often implying the negligence of that activity by developers. Moreover, with the advance of automated verification tools, formal methods, such as Event-B, are increasingly attracting the attention of software companies. However, it is still difficult to convince developers to adopt them, because they are not acquainted with some mathematical concepts. Thus, this paper presents a proposal for the inclusion of Event-B within Iconix, giving rise to BIconix, an object-oriented development process that supports automatic inconsistencies formal verification. More specifically, this thesis addresses the translation of the four existing diagrams in Iconix (classes, use cases, robustness and sequence) to EventB, and show how this formalization can assist the verification activity in well-defined check points of the proposed process.
