Abstract: Maintenance is an important phase of software lifecycle. Software maintainability is a key aspect of quality to software, which directly impact how much effort and cost will be spent on related systems or productions. Currently, it has become an essential point to evaluate whether a software system or productions is successful. People pay more and more sight on the software maintainability and give consistent analysis and research and try to figure out how to improve the software system maintainability. Answer can be extracted from each phase which composes the whole software lifecycle. This article focuses on the impact to maintainability from software design sight, and gives out a solution on improvement and optimizes on the software maintainability.
