Abstract. Declarative approaches have been proposed to counter the limited flexibility of the imperative modeling paradigm, but little empirical insights are available into their actual strengths and use. Our previous work has shown that end-users can effectively model and execute a declarative process with a considerable spectrum of constraints. However, what is still unclear is how effectively end-users are able to handle unforeseen events that can occur during run-time. This paper describes the design, execution, and results of a controlled experiment in which subjects have to execute a process with varying levels of events. The results suggest that our subjects, while being able to effectively handle constraints, have difficulties to handle unforeseen events during run-time. This outcome supports the argument that declarative processes require more experienced people, especially when dealing with unforeseen events.
