Tropos: A Requirements-Driven Methodology for Agent-Oriented Software

Software systems of the future will have to perform well within ever-changing organizational environments. Unfortunately, existing software development methodologies (object-oriented, structured or otherwise) have traditionally been inspired by programming concepts, rather than organizational ones, leading to a semantic gap between system and its operational environment. To reduce this gap, we propose a software development methodology named Tropos which is founded on the i* organizational modeling framework. i* offers the notions of actor, goal and (actor) dependency. Tropos uses these concepts as a basis to model early and late requirements, architectural and detailed design for a software system. The paper outlines Tropos phases through an e-business example. The methodology complements well proposals for agent-oriented programming platforms.
