“…In addition to knowledge of team members' roles and responsibilities and the ability to monitor performance, team members need to know who should step up, when to step up, or how (Salas et al, 2005). Some have argued that backup behavior makes a team a team (McIntyre & Salas, 1995), and empirical research has shown that it does improve performance (Porter et al, 2003) and minimize error (Johnston & Briggs, 1968). Especially critical under periods of high workload, members of successful teams monitor each other's performance and identify deficiencies (e.g., workload has surpassed one's capabilities) so as to provide backup behavior in the form of (a) feedback or coaching or (b) assistance to ensure team goals are achieved (Marks, Mathieu, & Zaccaro, 2000;McIntyre & Salas, 1995;Porter et al, 2003).…”
