An integrated framework for the analysis of dependable interactive systems (IFADIS): Its tool support and evaluation

This paper discusses a method for the analysis of dependable interactive systems using model checking, and its support by a tool designed to make it accessible to a broader community. The method and the tool are designed to be of value to system engineers, usability engineers and software engineers. It has been designed to help usability engineers by making those aspects of the analysis relevant to them explicit while concealing those aspects of modelling and model checking that are not relevant. The paper presents the results of a user evaluation of the effectiveness of aspects of the tool and how it supports the proposed method. The tool was constructed while both authors worked in the Human Computer Interaction Group. Department of Computer Science, University of York, UK.
