In this paper, we combine the Box Structure Development Method (BSDM) [Principles of Information Systems Analysis and Design] and CSP [Communicating Sequential Processes], with the goal of integrating them into an industrial software development environment. BSDM forms an ideal bridge between the actual system being developed and the abstract models used for formal analysis. CSP complements BSDM by providing the mathematical framework for formal verification, together with its model checker FDR. We present generic algorithms for translating specifications from BSDM into CSP, illustrate how they can be formally verified using FDR and summarise their effectiveness in practice.
