The core objective of a post-incident review (PIR) is to identify gaps and weaknesses in the response process.
This includes missteps, delays, communication failures, or policy limitations - all of which provide insight to improve future incident handling.
"Post-incident reviews focus on identifying root causes and areas for improvement to enhance the organization's preparedness for future incidents."
