A control flow notation has been proposed for the Doctor's appointment scenario, and a workshop was organized to conduct paper prototyping experiments for evaluation. We wished to find out if the notation is understandable and what level of expressiveness can be achieved. Other project participants were given a set of composition exercises, and they answered a set of questions to evaluate the notation. Later the exercises were repeated involving additional persons without IT background. The flow-based approach was found to be feasible, but some shortcomings of the notation were pointed out. More thorough testing will be carried out after the notation has been revised.
