Abstract. Innovative e-commerce ideas have often floundered on an inadequate analysis of the expenses and benefits of the idea and an inadequate integration of the required e-business processes with other business processes. We present a requirements analysis and business process design approach that focuses on the analysis of the expenses and benefits of the e-commerce idea to all actors involved. We map this value viewpoint to the available business processes of the actors and show how to derive an economically feasible cross-organizational business process design.
