Overview
A PIR (often used interchangeably with 'post-mortem') is the final stage of the incident management lifecycle. It provides a structured way for the team to reflect on the event and ensure that the organization becomes more resilient as a result.
Key Sections
- Executive Summary: A high-level overview for stakeholders.
- Timeline: A detailed sequence of events from detection to resolution.
- Impact: The number of users affected and the duration of the outage.
- Root Cause: The underlying reason for the failure.
- Action Items: Specific tasks to prevent recurrence, with owners and deadlines.
Importance
Without a PIR, the same incidents are likely to happen again. It is the primary mechanism for continuous improvement in operations.
