An Approach of Crossover Service Goal Convergence and Conflicts Resolution

With the increasingly complex requirements of users in modern society, it is difficult to meet the complex goals of users by services from a single domain, and thus crossover service convergence, which aims to provide deep service integration and innovation across boundaries of industries, organizations, and value chains becomes an urgent need. Goal convergence is the first step to guide the process of crossover service convergence. However, there is currently no systematic theory and method to address this problem. In this paper, we propose a method to support goal convergence of crossover services. Firstly, two goal models from different domains are converged according to new user requirements. We then detect inconsistencies of goal models and resolve potential conflicts. We have developed a goal model convergence tool to help requirements analysts perform goal convergence in a visualized way. A case study is presented to show the feasibility of the proposed method.
