Aspect-oriented approaches are available for various phases of software development such as requirements, design, and implementation. Yet, moving from one phase to the next with aspects remains a challenge seldom studied. In this paper, we present an iterative, concern-driven software en- gineering approach that is based on a tool-supported, semi- automatic transformation of scenario-based, aspect-oriented requirements models into aspect-oriented business process design models. This approach is realized by a mapping from Aspect-oriented Use Case Maps (AoUCM) to Adore busi- ness process models, allowing for the continued encapsula- tion of requirements-level concerns in design-level artifacts. Problems detected during the design phase can be rectified in the requirements models via several feedback loops that support iterative model development. We discuss the trans- formation process and illustrate, as proof-of-concept, our contribution on the PicWeb case study, a SOA–based imple- mentation of business processes for pictures management.
