It doesn't seem like a survey of stakeholders will be conducted. However, there has been a broader survey (done by the CES) of how much our outputs are being used by member states.
Many of the Standards Group outputs scored very highly in the results, for example the GSBPM, which is no surprise. Additionally, the output from one of our activities on "Implementation Standards in the Context of GSBPM" also scored very well, which is good to see.
