The document outlines the development of a diagnostic tool to allow countries to benchmark their progress on achieving the 17 Sustainable Development Goals (SDGs). The tool would identify gaps in achieving the 169 targets, help formulate policies to address the gaps, estimate resource needs, and allocate resources from public and private domestic and external sources through a national plan. An example is provided showing how the tool could analyze gaps and resource allocation for SDG 9 to build resilient infrastructure and foster innovation.
