Advanced Information Systems Engineering

Information systems of the future will have to better match their operational organizational environment. Unfortunately, development methodologies have traditionally been inspired by programming concepts, not organizational ones, leading to a semantic gap between the system and its environment. To reduce as much as possible this gap, this paper proposes a development methodology named Tropos which is founded on concepts used to model early requirements. Our proposal adopts the i* organizational modeling framework [18], which offers the notions of actor, goal and (actor) dependency, and uses these as a foundation to model early and late requirements, architectural and detailed design. The paper outlines Tropos phases through an e-business example. The methodology seems to complement well proposals for agent-oriented programming platforms
