Abstract: In this paper, we suggest a requirement engineering process that generates a user interface prototype from scenarios and yields a formal specification of the system in form of a high-level Petri net. Scenarios are acquired in the form of sequence diagrams as defined by the Unified Modeling Language (UML), and are enriched with user interface information. These diagrams are transformed into Petri net specifications and merged to obtain a global Petri net specification capturing the behavior of the entire system. From the global specification, a user interface prototype is generated and embedded in a user interface builder environment for further refinement. Based on end user feedback, the input scenarios and the user interface prototype may be iteratively refined. The result of the overall process is a specification consisting of a global Petri net, together with the generated and refined prototype of the user interface.
