Overview

Impact analysis identifies what will be affected by a change to a CI. This skill covers:

• Using CMDB relationships to trace impact paths
• Identifying affected business services
• Mapping CI criticality to business impact
• Quantifying change risk based on CI relationships
• Generating impact reports for CAB review

When to use: Before implementing changes, during incident triage, for capacity planning, or when assessing new deployments.

Value proposition: Accurate impact analysis prevents unexpected outages, reduces change failures, and enables informed risk decisions.
