Eventually I found the report which is the subject of the last post - report number 090101. It does NOT contain a clear statement of methodology NOR a clear definition of the evaluative terms "good", "adequate", "inadequate". There is no discussion of how the SCRs promoted organisational learning. As I thought, they are assessing means not ends. On the positive side there is some analysis of the characteristics of the cases on which the reports are based, but the overall conclusions are unsurprising and uninspiring.
