The Relationship Between Teamwork Knowledge And Teamwork Behavior, Jeeun Yi, Glenn E. Littlepage Oct 2018

The Relationship Between Teamwork Knowledge And Teamwork Behavior, Jeeun Yi, Glenn E. Littlepage

River Cities Industrial and Organizational Psychology Conference

Many organizations utilize a team-focused work structure in the workplace. Researchers have studied how working as a team can improve organizational outcomes such as productivity and employee satisfaction (Katzenbach & Smith, 1993). However, not all teams make positive outcomes (Hackman, 1998). Previous research has shown that effective teamwork can facilitate group and organizational effectiveness (Salas, Stagl, Burke, & Goodwin, 2007). Various models of teamwork process have been developed (Marks, Mathieu, & Zaccaro, 2001; Rousseau, Aube, & Savoie, 2006; Salas, Sims, & Burke, 2005). A meta-analysis found a consistent relationship between the ten dimensions of teamwork identified by Marks et al. (2001) and team performance (LePine, Piccolo, Jackson, Mathieu, & Saul, 2008). Previous research has shown that team members with high cognitive ability, certain personality characteristics, and job-related knowledge and skills may contribute to better performance (Devine & Philips, 2001; Mathieu & Schulze, 2006; Morgeson, Reider, & Campion, 2005; Neuman & Wright, 1999). Among those characteristics, having aggregate member knowledge of teamwork showed a positive relationship with team performance (McClough & Rogelberg, 2003), but the relationship between individual teamwork knowledge and individual teamwork behaviors has not been widely examined. In this study, the relationship between teamwork knowledge and teamwork behavior will be examined. Building on the main relationship, this study will also investigate the impact ...
