The PERC manual: Learning from disasters to build resilience - a simple guide to conducting a post event review

In this methodology manual, the Post-Event Review Capability (PERC) process is explained for individuals and organizations looking to conduct a systematic and holistic evaluation of a disaster. This manual is aimed to disaster risk practitioners and researchers.

The PERC is a systematic framework for the analysis of a disaster event, focusing on how a specific hazard event became a disaster. PERC is typically conducted and published within a year of the disaster, though it can be used in other ways or in other timeframes as necessary. The PERC process evaluates the successes and failures in the management of disaster risk prior to the event, disaster response and post-disaster recovery. It uses a system-wide approach to review disasters, analyzing across scales and sectors, and all aspects of the disaster management cycle – prospective and corrective risk reduction, preparedness, response, and recovery. It provides a bird’s-eye view of why the disaster occurred and how resilience can be built.
