Abstract
Controls have to be implemented in all stages of systems development. They are particularly critical in input design (to prevent Garbage In-Garbage Out) but such operational controls must not be unduly stressed at the cost of those in other phases of system development. This chapter begins by identifying the areas of risk using the ‘onion-skin’ approach suggested by Wong (1981), which provides a framework for systematically identifying computer-related risks (see figure 9.1). Controls to prevent and detect errors and incursions are presented in subsequent sections of the chapter.
