Consideration must be given to whether separate implementation strategies are necessary for the policy to be effective for each relevant group. Although employed to various degrees in a majority of OECD countries (including Finland, Switzerland, Sweden, New Zealand, Turkey, the United Kingdom and Korea), GIAs have yet to become routine steps in public policy making. Examples of cases with highest proven record of GIA implementation include Catalonia, where GIA is fully legislated (203 GIAs performed in 2012) and Sweden, where GIAs have not been regulated and are being carried out with different methodologies and at all levels (Boman, 2013), Ongoing challenges related to methodological concerns, lack of expertise to conduct such assessments, and the absence of precise guidelines remain (Ibid). Within the private sector, however, comparable gender analyses have a long history of providing information to corporations related to purchasing practices and service preferences of men and women consumers.
