A key problem in the development of information systems is understanding features of the development process. To this end,
in recent years, considerable interest has been focused on modelling processes. In this paper, the results of an empirical
investigation into the use of prototyping in information systems development is described. Nine prototyping processes across
eight different sites of varying size were analysed and data relating to each process collected. The notation of Role Activity
Diagrams (RADs) was used to capture each of the nine processes. Analysis of the interactions in each process revealed that
the project manager interacted with the prototyper far more often in large developments than in small or medium-sized developments.
However, significantly more interactions between the project manager and end-user were found in small-sized developments than
for any other sized site. The study demonstrates how measures of business models can aid analysis of the process rather than
the product and highlights the need for more empirical investigation into this and other facets of the development process.
A number of lessons have been learnt from our analysis; these we also explain.
