Abstract: Software drift is a common phenomenon existing in software development processes, which can influence development process quality and software product quality. In this paper, the basic definition, relevant concepts and forms of software drift were expatiated primarily. According to the effects on development processes, a taxonomy of negative drifts was studied so as to explain why these drifts were generated in different phases. Then, the relations between negative drifts and software quality attributes were summed up, and the evaluation of their impacts on software quality was qualitatively analyzed. At last, some key problems such as control strategies and metrics for software drift that need to be solved were introduced to guide the future work.
