Rapid Prototyping With Fourth Generation Systems – An Empirical Study

Discusses experiences on the development and use of horizontal and vertical prototypes. Explains the difference. Resolves that horizontal prototypes can be developed with ′little effort′, but end users are reluctant to become involved in the development process. Contrastingly resolves that vertical prototypes appear to stimulate constructive response. Reasons that developers should be aware of the tacit knowledge which plays an important part in users′ work practices and should be involved early in the development process. Proposes three techniques to meet the requirements – participation, simulation and evaluation.
