This document presents a framework for analyzing public investment management. It outlines eight core features that a well-functioning public investment system should have: 1) investment guidance and screening, 2) formal project appraisal, 3) independent review of appraisals, 4) project selection and budgeting, 5) project implementation, 6) project adjustment, 7) facility operation, and 8) ex-post evaluation. It then provides diagnostic indicators to assess where a country's actual public investment system performs well or poorly compared to the desirable features. The framework aims to inform reforms by identifying performance gaps between desired features and reality.
