  Agile principles were originally developed for small projects but are now widely used in larger projects with hundreds of developers. Teamwork quality is essential in any development work, but how does teamwork quality differ in small and large agile projects? We report from an explorative survey with 64 agile teams and 320 team members and team leaders, from 31 teams in small projects and 33 teams in large projects. For small projects, teamwork quality was considered by both team members and team leaders to primarily affect product quality. For large projects, the effect of teamwork quality on product quality was positive when it was rated by team members but was negative when rated by team leaders. At a finer granularity, the six dimensions of teamwork quality that we investigated affected team performance differently in small and large projects. These findings question to what extent findings from previous studies on teamwork in agile development in small projects apply to large projects.

  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. The Web extra at https://extras.computer.org/extra/mso2016040106s1.pdf details the sources and research methods the authors employed.

  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.

  How to make teams perform well is increasingly important in software development, as agile development methods prescribe development in small teams. Team performance has been studied in a number of research fields, and there are many models of what enables team performance. A central question then is how relevant these models are for agile development teams. This article investigates the following research question: What factors do agile software practitioners perceive to influence effective teamwork, through a focus group study with 92 participants in 18 groups. The main findings are that what agile practitioners perceive foster and hinder team performance seems to comply well with what is stated in an existing research-based model. However, agile practitioners seem to place insufficient focus on backup behaviour. Agile practitioners place much emphasis on physical and technical infrastructure of the development team as enablers of team performance

  Context: Most of the software organizations that use agile methods organize daily team meetings. Aim: Our aim was to understand how daily meetings are conducted and identify obstacles that reduce their efficiency. Method: We observed 56 daily meetings and conducted 21 interviews in three different teams in two countries. We used the repertory grid technique in the interviews and to analyze the results. Results: We identified thirteen obstacles. The four most prominent ones were: (1) The daily meetings lasted too long (on average, 22 minutes instead of the scheduled 15 minutes). (2) In the meetings that were not self-organized, team members reported to the Scrum Master instead of sharing information among all team members. (3) The interruption caused by daily meetings required substantially more time than the actual meeting time due to overhead before and after the meetings. (4) Several team members had negative attitudes towards the daily meetings. Conclusion: Organizers of daily meetings should evaluate whether the obstacles we have identified are present in their organization and consider our suggestions to remove or reduce these obstacles.
