 The Team Effectiveness Model for Science, TMS, is a comprehensive framework that helps form and develop effective science teams by focusing on three key areas, mindset, behavior and structure. The model emphasizes the importance of shared values, assumptions and norms among team members, which serves as the foundation for developing and maintaining effective team functioning. Additionally, it provides a structured approach for integrating the science and relationship aspects of a team, as well as providing guidance for designing processes and structures that are aligned with the team's values, assumptions and norms.
