Abstract

The i *framework was developed to support requirement analysis and high-level design in an agent-oriented system development paradigm. It models intentional dependency relationships among strategic actors and their rationales. As actors depend on each other for goals to be achieved, tasks to be performed, and resources to be furnished, the trust relationships among these actors need to be considered to reason about the opportunities and vulnerabilities these dependencies bring. The concept of softgoal is used to model quality attributes for which there are no a priori, clear-cut criteria for satisfaction, but are judged by actors as being sufficiently met (≪satisficed≫) on a case-by-case basis. In this paper, trustworthiness is treated as a softgoal to be satisficed from the viewpoint of each stakeholder. Contributions to trustworthiness are considered using a qualitative reasoning approach. Examples from the smart card domain are used to illustrate.
