Abstract: Software-architecture-level maintenance evaluation based on scenario mainly relies on two technologies: elicitation of the scenarios and impact analysis in architecture level. This paper focuses on the impact analysis in architecture level. It studies the challenges that impact analysis faces, and presents the solution. The study in this technology can improve the efficiency of the many software-architecture-level evaluation methods, and can improve system maintenance.

Key words: impact analysis, software architecture, maintenance
