The increasingly global nature of financial markets and institutions means that the collection and management of information on which decisions might be based are increasingly complex. There is a growing requirement for the integration of information flows at individual and departmental levels, and across processes and organisational boundaries. Effective information management is an important contributory factor in the efficiency of such institutions, though there are many associated problems that do not have obvious or simple answers. This paper discusses the problem of information gathering in complex business environments and considers how use cases can help to alleviate the problem using an example of a multinational organisation. Such organisations often require information systems that can support regional differences. However, management requires consistent and uniform representation of information. The example shows that use cases can be a helpful mechanism for capturing user requirements that accommodate both regional properties as well as their organisational commonalties.
