A Tool Supported Methodology for Designing Multi-Perspective Enterprise Models
Development and organisational implementation of corporate information systems are still afflicted with severe economic problems. They are partially due to the fact that advanced software engineering methodologies are rarely applied. Moreover requirements analysis often does not produce satisfactory results. While user participation is widely agreed to be a prerequisite of successful system design it is often hard to accomplish. System analysts and the various users have different views of an organisation which makes it difficult to communicate efficiently. Object-oriented enterprise modelling can contribute to improve this situation. It encourages conceptual design using semantically rich domain level concepts. This is not only a prerequisite for implementing highly integrated information systems. Enterprise models are also suited to establish a common universe of discourse for both system developers and users by providing illustrative representations of organisations which are based on a solid software architecture. The paper introduces a conceptual framework for the design of multi-perspective enterprise models which does not only incorporate advanced object-oriented methodologies but also takes into account epistemological, organisational and economic aspects. A computer based integrated design environment is presented that is based on this framework. It supports the interactive development of object-oriented conceptual models. For this purpose it provides graphical representations of static as well as dynamic aspects of organisations and allows for analysing the effectiveness of office procedures.
