In a modern business process, documents are important carriers of information between organisations. Document management solutions are increasingly based on structured document formats, such as XML (Extensible Markup Language). However, deployment of structured documents is a complicated task, which requires systematic analysis of requirements of all groups either producing or using documents. In this paper, we describe a method for modelling user roles in document analysis. The method is used to support analysis of requirements of individual and organisational users of documents as well as analysis of organisational needs related to security and access control.
