CI Relationship Mapping

Overview

CI relationships form the backbone of CMDB value. Without relationships, CIs are isolated islands of data. This skill covers:

• Understanding relationship types and their semantics
• Creating and validating relationships between CIs
• Analyzing dependency chains for impact assessment
• Detecting orphan CIs that lack relationships
• Maintaining relationship health over time

When to use: When modeling service dependencies, preparing for change impact analysis, auditing CMDB completeness, or troubleshooting service outages.

Value proposition: Well-mapped relationships enable accurate impact analysis, reducing change failures by up to 50% and decreasing MTTR during incidents.
