Optimizing Requirements Elicitation with an i* and Bayesian Network Integrated Modelling Approach

In today´s web-based environment, strategic actors collaborate and compete to further its interests and opportunities. In this paper, we propose optimizing the requirements elicitation process through the combined use of the i* modeling framework with the quantitative risk analysis model of Bayesian Network (BN), so that strategic actors can estimate the potential opportunities and risks of concerned high-level goals within a multi-agent network. Major content of the paper include: a brief introduction and comparative study of the meta-model of i* and BN; a set of heuristic rules for mapping an i* model into a Bayesian network; the reasoning process of the i* and BN integrated approach. We use the widely cited meeting scheduler example in the literature to illustrate the proposed approach.
