Very clear thinking Harold - I think it's very important that you first take some distance and help the readers take a view on how work has changed and will be changing. That step is often forgotten keeping people trapped in the 'learning box' or learning bubble as Jos Arets and Charles Jennings explain in their new book. Some people only focus their effort 'fighting' 70:20:10 as concept because of lack of research supporting it's value. Last weekend I thought: how much scientific evidence based on research is available that a hammer really works? If there is a lack of evidence I suggest we stop using them. Keep writing and sharing Harold
