The collaboration-based approach is a powerful means to develop modularised systems by stepwise refinement. In this paper we introduce a new approach to realise a collaboration-based design. Our approach is based on the well-known observation that the knowledge about inter-object collaborations cannot be localised within objects but cross-cuts many objects. Such cross-cutting concerns are effectively addressed by applying the separation of concerns principle. We have, therefore, employed Aspect-Oriented Programming (AOP) to build collaboration-based designs. In the paper we illustrate and discuss our aspect-oriented approach both for the horizontal (i.e. the collaborations) and vertical (i.e. the refinements) dimensions. Although the example implementations are based on AspectJ0.4beta7 from Xerox PARC, the approach is generic enough to be implemented using other AOP techniques.
