Analyzing the Use of an Enterprise Model as a Stakeholder Requirements Model: An Experiment

There are several possible representations for stakeholder requirements, such as goal models, scenarios, and natural language. This paper analyzes the use of an enterprise model as a stakeholder requirements model. We conducted a quasi-experiment with 29 graduate students who received either a textual problem statement or an enterprise model, representing the stakeholder requirements, and refined it into use cases, representing the software requirements. The subjects were evaluated considering the use case quality and the time spent, for two different scopes. The results indicate that the mean quality of the use cases created using an enterprise model was equal to or greater than the mean quality of the use cases created by the other groups. In addition, the mean time spent to create a use case using an enterprise model was equal to or less than the mean time needed for the other groups.
