In recent times, there has been an increased requirements for software to be distributed. The well-known Fusion development method, however, can only be used to develpp sequential reactive systems, and certain restricted kinds of concurrent systems. In contrast, the Unified Modeling Language (UML) provides a rich set of notations that can be used to model systems that are distributed. In addition, UML provides the ability to introduce rigor into diagrams through its constraint language OCL. In this paper, we present a UML-based Fusion analysis phase by way of a simple bank case study, and we discuss some enhancements that were made in additon to a mapping of notations; our proosal is the first step towards providing a Fusion-based analysis phase which supports high-level modeling of distributed systems.
