Those who know me, know I am critical of the continued use of Roger's Diffusion Curve as a means of telling people how and how to plan for the spread and adoption of good practice. If you read Roger's work in depth you will understand its limitations.
One of these is the lack of attention to context. It's fairly obvious to anyone involved in spread and adoption of good practice that leadership, organisational culture and readiness to change etc. are all important in the process. The problem is, although many models and frameworks are drawn up to show how context is important - which is an excellent first step - there is a shortage of published work on the topic.
A key problem is that those who publish ignore the contextual factors. A recent review paper by Emmens, Weiner & Fernandez looks at this issue.
