Software Prototyping: Designing Systems For Users
Phyllis Bova Spies · Library Hi Tech · 1983
The prototype model (the implementation of a skeletal system that is enhanced during interaction with users) represents a major change in the software development process. This change is in direct response to higher costs, greater expectations of online systems users, new technologies for development, and the more challenging problems posed by online, interactive systems. The “traditional systems development methodologies tend to evolve toward increasing control and specificity, especially when confronted by higher uncertainty.” In contrast, new methodologies, such as prototyping, exploit the dynamic process of change and variability in both the user and system environments.
