Assessing organizational capacity for diffusion: A school-based social network analysis case study

•Organizational networks are not neutral; they either impede or amplify diffusion of innovation.•Social network analysis (SNA) is a powerful approach for assessing organizational capacity for diffusion of innovation.•Administrators have a responsibility to cultivate effective teacher networks capable of diffusing innovation.•Organizational leaders find social network analysis highly accessible and useful for program planning. The purposeful design of social networks is increasingly recognized as a fundamental organizational improvement strategy. In the PK-12 education sector, school-based teacher collaboration is the primary vehicle through which educators are able to gain access to essential social capital, and through which leaders promulgate diffusion of innovation and continuous organizational learning. In partnership with school administrators, the authors undertook an evaluation to examine the size, structure, and composition of school-based networks. Social network analysis (SNA) was used to measure and visualize connections (or lack thereof) of ties between teams and between educators. Isolate and disconnected network actors were revealed through visual inspection of the sociograms. Administrators used findings to reconfigure team membership to enhance teacher ability to give and receive support and collaboratively problem-solve, and to ensure greater capacity for diffusion of instructional innovation and organizational learning. This paper contributes to the field’s understanding of how evaluators and organizational leaders can use SNA to measure, visualize, and more purposefully design effective patterns of connection between people through which professional knowledge, support, and innovation will travel.
