The approach using the joint goal model is proposed for software reuse. Common goals are important to build the joint goal model. However the related works do not mention techniques for identifying the common goals. In this paper, we propose a technique to identify common goals. They are using the similarity of goals and the three proposal rules. The experiment using the goal models of the domain of television and social network system and employment support system shows the accuracy of the proposal rules. The experiment using the goal models of the domain of camera shows the accuracy of the proposal technique.
