Below is the 2011 Survey by Version One. One might like yet better participants in the survey, but still I think it is generally indicative of the main trends.
Some key points to me:
* We have a long way to go
* Too many people “rolling their own”
* Despite the stupid things, still a fair amount of success
* Key prospective reason: Accelerate time to market (achieved by 71%)
* Key retrospective benefit: manage changing priorities (arguably a subset of faster time to market): Achieved by 84%
