A methodology for developing integrated information systems based on ERP packages

This paper describes a methodology for the structured development of manufacturing information systems based on a collaborative action research project. The methodology starts from the premise that a company has an enterprise resource planning (ERP) system in place. It can then be used to determine the optimal method for achieving a particular business requirement. The methodology has seven decision points, each of which relates to a different outcome. The methodology is supported by a series of questions to assist users in making appropriate decisions. The paper also describes a series of structured interviews with practitioners from industry. These were undertaken in order to verify the usefulness of the methodology. These interviews show that there is a requirement for tools to assist in the ongoing development of information systems in manufacturing industry. Furthermore, the interviews suggest that the methodology is a useful tool, particularly for relatively inexperienced manufacturing information system practitioners
