Introduction: The GNSO Standing Committee on Improvements Implementation (SCI) is tasked to review and assess the effective functioning 'on a periodic timescale for all recommendations [stemming from GNSO Improvements] in order to identify possible issues and/or improvements'. One of the recommendations that has been in force for over a year is the GNSO Working Group Guidelines (adopted by the GNSO Council on 16 March 2011). As a starting point to identify possible issues and/or improvements, the SCI has developed this survey to obtain input from GNSO Working Groups that have used the GNSO Working Group Guidelines as well as other related sections of the GNSO Operating Procedures, such as Statements of Interest (SOI) as part of their operations.
