We studied 80 software development teams from 28 labs worldwide (including labs in Brazil, China, Denmark, France, Germany, India and the United States). The labs varied in size (employing between 20 and 5,500 software developers), and each team contained up to nine members. Our research included those software development projects that were completed within 12 months prior to data collection. A total of 392 managers, team leaders and team members participated in the study, and data from multiple respondents were used to ensure the validity of results and to overcome common method bias.
