“…Advocating a comparable index across countries and methodological soundness, the IBP conducts primary data questionnaires that are completed by independent researchers in each country and blindly reviewed by two country experts, acquires feedback from government, and makes final decisions scored by the IBP team based on citations and attaches them to relevant documents (De Renzio & Masud, 2011;IBP, 2012).
