Marks, Mathieu, and Zaccaro (2001) advanced a theory and framework of team processes that has garnered much attention and guided numerous investigations. They proposed that 10 first-order constructs (e.g., strategy formulation, coordination, conflict management) would map to three second-order constructs (i.e., transition, action, and interpersonal). Despite the popularity of this framework, we are unaware of any validated multiitem measures of the team processes they identified. Accordingly, we develop and demonstrate content and construct validity of 50-, 30-, and 10-item versions of a survey measure of team processes. Using data from over 700 teams, we test Marks et al.’s higher-order model and find results that are largely consistent with both their 10 first-order dimensions and the 10:3 second-order framework. Using samples of global virtual knowledge teams and health care employees, we provide evidence of the discriminant validity of our team process measure versus a measure of team empowerment. We provide recommendations for the use of these measures in future research and practice and encourage their use as part of a portfolio of measures of team processes.
