The Impact of Peer Code Review on Software Maintainability in Open-Source Software: A Case Study

Recently, open-source software (OSS) has become a considerably popular and reliable source of functionality corrections. OSS also allows developers to reduce technical debt in development. However, previous studies have shown that the main problem within development is lack systematic processes formal documents related system development, such as requirements, designs, testing. This feature causes problems quality, those security maintainability. In this research, authors focused on software’s maintainability because attribute greatest potential cost increase productivity process. There currently no existing research examines whether pay attention To better understand how improve maintainability, aims answer question: “Are interested under modern code review projects?” question, investigated process which changed based comments maintenance collected sub-characteristics associated with from literature. The examined two projects: Eclipse Qt. results suggest number revisions due issues was moderate tend quality. direction could be observed increasing modifications given maintenance-based over years. Therefore, an implication possibility project are
