Abstract: The process to model the behaviors of virtual group has been divided into two stages, task interaction design and abstraction of the model. In the first stage, the task process is designed through task decomposition, interaction design and behaviors determination based on task decomposition. In the second one, the organization synergy model is presented by designs on three different levels, the structure level, the element level and the relation level, based on the design of the primary analysis. The method provides a framework to instruct the modeling work of virtual group organization synergy.

Key words: organization synergy, description logic for tasks, interaction design, model abstraction
