Experience from computer supported prototyping for information flow in hospitals

Special-purpose languages have several advantages for rapid prototyping purposes: they allow very fast development of applications; facilitate the dialogue with end users in the specification work; and simplify the work of updating the prototype iteratively. We have been working with a modelling language based on the concept of information flow in organizations, and a number of software tools which support this language. Previous papers from the project have described the first generation of tools; the present paper describes the experience from using the system in a large scale development effort, as well as the second generation of support tools.
