The applicability of the i* approach for organizational modeling has been compromised by the complexity of the resulting models. To solve this problem an approach that use i* with Aspect Orientation is proposed. In this work we evaluate the understandability of five selected concerns of two requirements documents. The first requirements document was modeled by the i* approach and the other one by i* extended with aspects. To do this evaluation it was used abstract metrics that needed to be instantiated in both requirement documents.
