Team composition, or the configuration of team member attributes, is a key enabling condition for effective teamwork. A well-composed team has the required complement of knowledge and skills, while also considering how the individual differences of team members, such as personality traits, values, and demographics, combine to shape teamwork and, ultimately, team performance. Theories from social, personality, and organizational psychology are used to explain how team composition influences the attitudes, behaviors, and thinking of teams and their members. Team member attributes can range from malleable characteristics, such as knowledge and expertise, to relatively enduring differences between team members, such as demographic variables (e.g., race) or personality traits; attributes are often referred to as knowledge, skills, abilities, and other characteristics (KSAOs). A distinction is often made between surface-level and deep-level composition variables. Surface-level variables are readily detectable characteristics (e.g., race) or easily accessible information (e.g., professional background) that can shape perceptions prior to interaction as well as affect, behavior, and cognition as team members interact. Deep-level variables are underlying, psychological differences between team members, such as personality traits, that shape affect, behavior, and cognition as team members interact. In general, deep-level composition variables have a stronger and longer lasting influence on teamwork and performance than surface-level variables. In team composition research, the unit-level configuration is of interest. Different models and operationalizations are used to capture how characteristics of team members combine to shape teamwork and performance. They range from simple operationalizations, such as the team mean on a specific trait (e.g., team mean conscientiousness), to complex diversity operationalizations that consider the alignment of multiple attributes (i.e., faultline strength). The goal of team composition research is to identify the KSAOs and configurations that shape teamwork and team performance, and then use this information in the management of teams. Teams can be composed ahead of time to maximize team effectiveness; members can be selected to have optimal fit with other team members and the team task. Team composition information can also be used to inform how to best manage a team over time; for example, how to reward the team. High-level information on team composition can be found in books on team effectiveness, with more comprehensive reviews in annual reviews and book chapters. Cutting-edge team composition theories and research are published in peer-reviewed academic journals, with secondary coverage in news outlets, trade journals, and magazines.
