This paper describes a use case driven approach for functional analysis/allocation and requirements flowdown. The approach utilizes use cases and use case realizations for functional architecture modeling, which in turn form the basis for design synthesis and requirements flowdown. We refer to this approach as the FAR (Functional Architecture by use case Realizations) approach. The FAR approach is currently applied in several large‐scale defense projects within BAE Systems Hägglunds AB. This paper also presents an empirical study where FAR is applied and evaluated in two large‐scale defense projects. Our results indicate that the FAR approach performs better than the previously used document based approach in the organization. © 2007, Wiley Periodicals, Inc. Syst Eng
