Scrum is a process framework used to develop complex software. As Scrum is one of the prominent approaches in agile development projects, it is significant to define the issues of quality in the Scrum method. In this paper, a systematic mapping approach is adopted to answer specific research questions through an objective procedure to identify the nature of quality issues in Scrum studies. For this purpose, a number of research studies are reviewed in electronic databases to find out about various quality issues related with Scrum. Here, the focus is on how these studies are affective in terms of defining such issues. A total of 53 research papers are examined in detail to answer nine research questions related to quality issues in Scrum. Finally, the responses to all research questions are provided along with suggestions to ensure quality in the Scrum. The results reveal that there is very limited research on people-related quality issues such as employee skills, satisfaction etc. However, process quality such as process effectiveness, conformity, visibility, acceptance etc. have received a lot of attention among researchers, whereas the product quality and project-related quality issues such as team performance, collaboration, etc. are also of interest among researchers.
