Explanation:

A post-incident review (PIR) is a process to review the incident information from occurrence to closure and to identify potential findings and recommendations for improvement1.The most important reason for an IS auditor to examine the results of a PIR is to evaluate the effectiveness of continuous improvement efforts and to ensure that the lessons learned from the incident are implemented and followed up2.A PIR can help an organization to eliminate or reduce the risk of the incident to re-occur, improve the initial incident detection time, identify improvements needed to diagnose and repair the incident, and update the incident management best practices1. Therefore, a PIR is a valuable source of information for an IS auditor to assess the maturity and performance of the organization's incident management process.
