The OECD’s Methodology for Assessing Procurement Systems (MAPS)
The Methodology for Assessing Procurement Systems (MAPS) was created by a joint initiative of the World Bank and the OECD in 2003. It has been used by dozens of countries, development banks, bilateral development agencies, and partner countries to assess their procurement systems.
MAPS aims to allow any country to assess the quality of their public procurement system and to support countries in implementing modern, efficient, sustainable, and inclusive public procurement systems in line with the UN’s Sustainable Development Goals.
