Scrum innovated the role of the scrum master in software engineering. The scrum master is envisioned in agile literature as the "servant leader" who serves the team in a multitude of different ways, which include promoting scrum, facilitating the team's functioning, and removing obstacles. However, empirical studies focusing on the role of the scrum master in practice are scarce. To address this gap, a Grounded Theory study with a mixed methods approach was carried out which included semi-structured interviews with 39 software practitioners and a questionnaire with 47 respondents. In this study, we present and describe the scrum master's role in agile projects in terms of (a) the grounded theory of the role of the scrum master which involves everyday activities of facilitating, mentoring, negotiating, process adapting, coordinating, and protecting; (b) the varying involvement of the scrum master in selected agile practices carried out by the team; and (c) a positive association between the presence of the scrum master and the frequency with which agile practices are carried out by the team. This study presents for the first time a multifaceted study of the multiple dimensions of the scrum master role and will enable practitioners to better manage expectations of this role in practice.

Nowadays, considerable attention is paid to agile methods as a means to improve management of software development processes. The widespread use of such methods in professional contexts has encouraged their integration into software engineering training and undergraduate courses. Although several research efforts have focused on teaching Scrum through simulating a software development project, they covered only the learning of programming practices within a Scrum team. Furthermore, few studies tackle nontechnical skills other than the development practices themselves. The work presented here introduces an original Scrum-based training model enhanced with agile coaching to maximize student performance. This was validated by a case study on a capstone project in a Scrum course. This paper summarizes the positive results of introducing agile coaching, which resulted in approximately 22% more coverage of software engineering practices. In addition, a survey data showed that, compared to students who did not receive coaching, coached students gained valuable insight into the internalization of Scrum, problem solving, and guidance by means of checkpoint meetings.
