“…Furthermore, in real life organizational contexts, characterized by complex multi-team systems (Marks et al, 2005), varying team life cycles (Hackman, 2012), and multiple team membership (O'Leary et al, 2011), as well as the methodological limitations imposed by the design of the NHS NSS, nesting individuals into teams was not possible in the current study. Thus we followed an approach adopted by others in the recent literature, analyzing and measuring team characteristics at the individual level (e.g., Bienefeld & Grote, 2013, Klein, Ziegert, Knight, & Xiao, 2006Lyndon et al, 2011). However, as noted below, future research should endeavor to overcome these operational challenges, building on the handful of existing studies that have examined the real team construct at the group level (Hackman & O'Conner, 2005;Wageman, 2001), to further explore ideas about real team and co-acting group membership.…”
