    Behavior-Driven Dynamics in Agile Development
    (Software Engineering 2020, 2020) Kortum, Fabian; Klünder, Jil; Schneider, Kurt
    This paper with the title Behavior-Driven Dynamics in Agile Development: The Effect of Fast Feedback on Teams\" was published as full paper in the proceedings of the International Conference on Software and System Processes (ICSSP) in 2019. Agile software development teams strive for fast and continuous feedback. Both the quality of the resulting software and the performance of the team require feedback. The performance of development teams is often addressed in retrospectives, which are not only part of the SCRUM framework, but also in various customized development processes. Reflecting on incidents during the last sprint helps the team to increase its performances, expressed by, e.g., efficiency and productivity. However, it is not only essential to identify volatile sprint performances, but also to characterize the root causes. The main reasons for low performance are often not visible, in particular when they are related to social-driven team behavior, such as communication structures, mood, or satisfaction. In this paper, we analyze whether automated team feedback about retrospective sprint-behavior can help the team to increase performances by additional awareness about the dynamic effects over time. In a comparative case study with 15 software projects and a total of 130 undergraduate students, we investigated the sustainable impact of feedback on human aspects. Our results indicate that automated feedback positively affects team performances – and customer satisfaction.

    Comparing Pre Commit Reviews and Post Commit Reviews Using Process Simulation
    (Software Engineering 2017, 2017) Baum, Tobias; Kortum, Fabian; Schneider, Kurt; Brack, Arthur; Schauder, Jens
    Previous studies found that two variations of change-based code review are used in in- dustry: Pre commit review and post commit review. Which one is better in a given situation is not obvious. So we asked: Are there practically relevant performance differences between pre and post commit reviews? How are these differences influenced by contextual factors? To assess these ques- tions, we designed and validated a parametric discrete event simulation model of certain agile devel- opment processes. Our analysis indicates that the best choice does depend on the context, but also that there are many situations with no practically relevant difference between both choices. We iden- tified the main influencing factors and underlying effects and condensed our findings into heuristic rules.

    Positive affect through interactions in meetings: The role of proactive and supportive statements
    (Software Engineering and Software Management 2019, 2019) Schneider, Kurt; Klünder, Jil; Kortum, Fabian; Handke, Lisa; Straube, Julia; Kauffeld, Simone
    Meetings often dominate software projects. Despite frequent dissatisfaction within meetings, many software engineers are not aware of the crucial importance about their behavior. This can set the tone for the entire project and influence the success. In a study based on 32 student development teams with 155 participants, we observed the participants’ interactions during the first internal team meeting. Analyzing the observations showed that constructive remarks had a positive impact on positive group affect tone. However, this effect can only be observed when supportive utterances followed constructive remarks. In the article, we show a complete mediation of this statistically significant effect, e.g., about seemingly subtle interaction patterns that influence group affect tone. We also propose practical interventions on how software projects could benefit from supportive meeting behavior. This summary refers to the article “Positive affect through interactions in meetings: The role of proactive and supportive statements” [Sc18] published in the Journal of Systems & Software in 2018 (vol. 143).
