A community of practice is defined as a "group of persons who share a concern, a set of problems, or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis" (Wenger, McDermott, & Snyder, 2002, p. 4). By linking these individuals who do not work together every day, a community of practice provides better knowledge sharing, reduces isolation, and fosters a form of collaboration that can lead to innovation (Mazer et al., 2015). Communities of practice are more flexible structures than are work teams or committees. They can be intra-or interorganizational and involve contact that is faceto-face, virtual, or a mixture of the two. Li and colleagues (2009) identified four characteristics of communities of practice in their systematic review: social interaction, knowledge sharing, knowledge creation, and identity building.
