Requirements models for large systems typically cannot be developed in a single step, but evolve in a sequence of iterations. We have developed such an iterative modeling process ...
We present a tool that provides effective graphical animations as a means of validating both goals and software designs. Goals are objectives that a system is expected to meet. Th...
Evolutionary prototyping focuses on gathering a correct and consistent set of requirements. The process lends particular strength to building quality software by means of the ongo...
When requirements models are developed in an iterative and evolutionary way, requirements validation becomes a major problem. In order to detect and fix problems early, the speci...
The User requirements of many web-based services are dynamically and continuously changing even during the service time itself. For that reason, web service companies always keep ...
