Implementation Team Members include individuals who directly or indirectly participate in implementation and support the Implementation Leads. Implementation teams can play a critical role in implementation (Dy et al. 2015; Klein and Sorra 1996; Means et al. 2020; Sue Dopson and Louise Fitzgerald 2006), because Implementation Leads are not as effective alone (Miech et al. 2018). The original CFIR (Damschroder, Aron, et al. 2009) elaborated that engaging team members tasked with implementing an innovation (or to be “first deliverers”), is an often-overlooked part of implementation; implementation teams ideally include deliverers and recipients. It is vital that Implementation Team Members are carefully and thoughtfully selected or respectfully encouraged to volunteer (Greenhalgh, Robert, et al. 2004; Edmondson et al. 2001; Pronovost et al. 2008) (see Implementation Process: Teaming and Engaging). The positive influence of having the “right people in the right seats” (Collins 2009) is strong; having the wrong people or missing key opportunities to engage important individuals on the team can have negative influence on implementation success.
