Executive Overview
ITIL 4 provides a modern, value-driven framework for IT service management (ITSM) that integrates DevOps, Agile, and Cloud operations into continuous service delivery.
1. Incident Management vs Problem Management vs Change Enablement
High-performing engineering teams maintain strict distinctions between service management practices:
- Incident Management: Restores normal service operation as rapidly as possible with minimal business disruption (workarounds, failovers).
- Problem Management: Analyzes recurring incidents to find underlying root causes and permanently prevent recurrence through known error databases (KEDB).
- Change Enablement: Maximizes successful service changes through peer reviews, automated canary testing, and risk assessment rather than bureaucratic gatekeeper CABs.
