In this report we are not seeking to reinvent this model but to review how to implement it effectively. Like so many apparently simple models we believe the model is sound but that understanding the complexities that lie behind it, and implementing it in
a way that is relevant to each organisation specific context, are the real challenges. This report is based on extensive desk research over the last few months and will be followed up with a series of interviews to look at the latest view ‘from the street’.
