Abstract
Although systems analysis for designing information systems shares much in common with business process mapping there are critical differences. Systems analysis methodology produces a logical model, which omits all extraneous detail (in a somewhat similar spirit to business process re‐engineering). The approach is based on two views: entity‐relationships for data modelling and data flow diagramming for representing functions (which is used in a similar context to process in BPR terminology). A third view using an event driven process network, which serves as a macro representation complementing the other two views, is advocated.
