Good Practice have published a really useful report on the 70:20:10 framework. It covers both the pros and cons and also looks at some of the competing (but very similar) approaches such as Dan Pontefract’s 3:33 from his book Flat Army. Definitely worth a download and a read (you have to tell them about yourself before you get your hands on the report but it’s worth doing).
In November 2014 we ran an E-learning Network event on ‘Social and Informal Learning‘ and that included an excellent session on 70:20:10 from Charles Jennings and Charles Gould. If you missed that then this report is worth downloading!
