Organisational and information system modelling for information systems requirements determination

Information system development lacks support for the organisational modelling and analysis which should be carried out prior to or concurrent with the requirements determination stage. We propose a new approach, termed Organizational Requirements Engineering (ORE), for requirements determination, which links together organisational and information system modelling, provides for re-engineering the organisation, and contains new diagrammatic methods both for organisational as well as information system modelling, which focus on the event. The method is designed to allow users to build their own organisational models. Parts of the method are supported by software tools. In addition, the results of an action research study show the ORE approach to organisational modelling compares favourably with that of data flow diagramming.
