The research I have reviewed indicates a need to understand context across disciplines (e.g., Health, Education, etc.). Multiple frameworks offer pathways to understanding from different perspectives (e.g., Fixsen et al, Damschroder et al. Pettigrew et al). I want to better understand, and impact, successful improvement/implementation practices within the organization to create sustainable practices at the project/school-level. I see parallels with the research around principals' and teacher s' impact on student achievement but, as in those studies, little is written of the parent organization. For example, what is it about the parent organization's leadership and improvement practices that maximize conditions for principals' and teachers' impact?
