In order to help business/system analysts conceptualize complex organizational changes and transform the models of existing information systems to meet new requirements, we explore the intersecting territories of agent-oriented software engineering, agent-based economics, and biological evolution, and create the Tropos Evolution Modeling Process for Organizations (TEMPO). Specifically, inspired by Kauffman's NKC model, we introduce the concept of goal interface into the Tropos methodology as the evolution frontier of an information system; within this interface, evolution is viewed as a process of negotiation between agents on goals both within and beyond the original organizational boundary; the information system is re-stabilized when agreements are reached between agents. TEMPO is illustrated with a real-life based case study that demonstrates how to evolve a retail website under the new European e-commerce legislation. TEMPO is further evaluated with a behavioral experiment, which proves that TEMPO is able to help analysts generate evolved information system models of higher quality at reasonable cost of time.
