This thesis is concerned with the use of prototyping during the development of information systems. Prototyping is a process which involves early practical demonstration of relevant parts of the desired system. This is carried out with a view to improving both the quality and timeliness of the target system. The quality of an information system is largely determined by its adequacy as a tool for human users. Prototyping serves to enhance the communication between developers and users, and through this to increase the suitability of the resulting information system. An investigation into the traditional phase oriented approach to systems development reveals that in certain circumstances it can result in incorrect or at best disappointing systems. The prototyping approach is examined as a possible alternative. Particular attention is paid to its use with respect to typical characteristics of information systems. This is followed by an investigation into all aspects of prototyping. One aspect, that of the construction of prototypes, is dealt with separately and includes an examination of a variety of tools and techniques. Three of these approaches form part of an experiment in building prototypes. Each method is used to build prototypes of the same system. This provides the opportunity to compare approaches in terms of time, cost, and ease of maintenance, with the existing system. Prototyping is used during the development of a genuine system in a commercial environment. Special consideration is given to both the organisation and the control of prototyping. This project is closely monitored and documented in detail. In conclusion, recommendations are made concerning the use of prototyping during information systems development. Further research areas are also highlighted.
