Abstract: The development of the domain information source facilitates the domain requirement. Few of the existing domain analysis methods nowadays can clarify the evolution process of domain requirements. Therefore, the method of gap analysis for domain requirement was presented in this paper, which was used to analyze the evolving process in a specific domain. This method analyzed the differences between the as-is requirements and the to-be requirements on the basis of the domain prototype system. Then, the problem-domains that need to be focused on in the evolution process of domain requirements were got, and the evolution model of the domain requirements can be built accordingly. This method is applied in the requirement analysis of banking system, and the effectiveness of the method has been well verified.
