Aspect-oriented Requirement Engineering provides approaches for eliciting and specifying the concerns and crosscutting concerns in the early stages of software development. In this paper, we present a case study in order to assess a model of the aspect-oriented multidimensional separation of concerns. With the case study, we review their features for elicitation, analysis and traceability of requirements, as well as some limitations of the model and how it can be adapted to the development process. Also, we discuss some issues that might endorse the development and evolution of this model.
