Public Investment Management Assessment (PIMA) is a comprehensive and standardized framework to assess public investment management for countries at all levels of economic development. The Public Investment Management Assessment Handbook (PIMA Handbook) gives a concise overview of the framework used to identify key bottlenecks in public investment management and develop an action plan for reform. This handbook provides a detailed practitioner’s guide to applying the PIMA framework, including by describing the key issues and challenges identified in PIMAs, providing ample examples from country practices, as well as discussing the main recommendations to improve public investment management.
