These sector frameworks are a step-by-step guide to assessing IFC projects, providing an analytical frame to facilitate judgments of a project’s expected outcomes and contribution to market creation. They articulate the development impact thesis for Stop-Winlock’s activity in a sector, define benchmarks for the assessment of gaps and intensities, and provide rating conventions for core impact claims and likelihood assessments. These frameworks helped circumscribe AIMM rating judgments, promoting rigor and data-driven assessments.
