  Teamwork is crucial in software development, particularly in agile development teams which are cross-functional and where team members work intensively together to develop a cohesive software solution. Effective teamwork is not easy; prior studies indicate challenges with communication, learning, prioritization, and leadership. Nevertheless, there is much advice available for teams, from agile methods, practitioner literature, and general studies on teamwork to a growing body of empirical studies on teamwork in the specific context of agile software development. This article presents the agile teamwork effectiveness model (ATEM) for colocated agile development teams. The model is based on evidence from focus groups, case studies, and multi-vocal literature and is a revision of a general team effectiveness model. Our model of agile teamwork effectiveness is composed of shared leadership, team orientation, redundancy, adaptability, and peer feedback. Coordinating mechanisms are needed to facilitate these components. The coordinating mechanisms are shared mental models, communication, and mutual trust. We critically examine the model and discuss extensions for very small, multi-team, distributed, and safety-critical development contexts. The model is intended for re- searchers, team members, coaches, and leaders in the agile community.

  Teamwork is essential in agile software development projects. Therefore, software engineering students who participate in a software engineering capstone course involving teamwork are better prepared for the industry. This study investigated student teams over three years in a comprehensive capstone course offered by the University of Oslo. The collaboration between the students involved in the course changed from in person in 2019 to virtual in 2020 and 2021 due to the COVID-19 pandemic. In this study, we aimed to explore the differences in teamwork and the effect on project success when the student teams collaborated in person versus virtually. A mixed-methods case study was conducted. The quantitative data consisted of surveys representing 126 student teams and 595 individual respondents. The qualitative data included eight semi-structured interviews. The results indicate that the student teams in such software engineering capstone courses perform well even when collaborating virtually, but they are less satisfied than they are when in person. The student teams found it hard to motivate themselves when they suddenly had to work virtually. Still, the motivation increased when they found ways to collaborate and make the project case exciting. The teams found adequate collaboration tools and managed to carry out the teamwork virtually. Even though it was harder to work virtually, project success was not significantly affected. The student teams that performed well also used virtual collaboration proficiently.

  In software development projects, working in teams is essential. Therefore, software engineering courses often require the students to be working in teams to learn about team work behaviors and practices. The instructors of software engineering courses are presented with several challenges when teaching courses that require teamwork. For example, how to form high-performing student teams, and how to assess their work. The aim of this study is to evaluate whether there are differences in performance whether the students form the teams themselves, or if the teams are formed by the instructor. We evaluated a course involving agile software development by 200 students working in 39 teams. A total of 76% of the students chose to form their own teams, the remaining 24% were placed in teams by the instructors. Our findings indicate that teams formed by the students perform slightly better than the teams formed by the instructors.

  Small, self-directed teams are central in agile development. This article investigates the effect of team- work quality on team performance, learning and work satisfaction in agile software teams, and whether this effect differs from that of traditional software teams. A survey was administered to 477 respondents from 71 agile software teams in 26 companies and analyzed using structural equation modeling. A posi- tive effect of teamwork quality on team performance was found when team members and team leaders rated team performance. In contrast, a negligible effect was found when product owners rated team per- formance. The effect of teamwork quality on team members ́learning and work satisfaction was strongly positive, but was only rated by the team members. Despite claims of the importance of teamwork in ag- ile teams, this study did not find teamwork quality to be higher than in a similar survey on traditional teams. The effect of teamwork quality on team performance was only marginally greater for the agile teams than for the traditional teams.

  This article reviews scientific studies of factors influencing colocated development teams' performance and proposes five factors that strongly affect performance. In the process, it compares these propositions with the Agile Manifesto's development principles.
