This paper examines the efficiency and effectiveness of a prescriptive systems development methodology in practice. The UK Government’s mandatory Structured Systems Analysis and Design Method (SSADM) was examined to determine its value to software projects. The evidence was collected from interviews with 17 project managers, discussions with participants on 3 large SSADM projects and from obser...
