Rapid application development in small unit settings

Abstract

Small units with specialised functions often have difficulty in developing information systems because of their unique and dynamic requirements, the smallness of their applications relative to the large inter-organisational networks, and the sheer numbers of such units, especially in government. Personal experience with the difficulty of establishing a suitable information system has led to the development of a methodology for endusers to develop their own applications with only the guidance of information technology professionals (ITPs) — here entitled ‘Small Unit Enduser Rapid Application Development’ or SERAD. A data base management system (DBMS) is used to manage data about ‘focal objects’ with status flags and queries/views at interface points through UDA (UserAction, DataEntry, ApplicationAction) cycles. The system which permits data entry almost immediately, not only eventually creates a full application, but also trains endusers in the process. The methodology leads ITPs and endusers through a sequence of exercises in systems analysis, tailored to minimise the time and effort input of ITPs despite the relative lack of IT training and concepts in endusers, with a view to rapidly creating dynamic, robust and sound information systems.
