## What Is Dependency Mapping?
What Is Dependency Mapping? Dependency Mapping the process of identifying and documenting the relationships and dependencies between IT components, applications, and services. Dependency maps reveal which systems rely on which other systems, enabling better change impact analysis and incident prioritization.

## Why This Matters for Your Business
Hidden dependencies are the cause of most "unexpected" outage cascades. When you update one application without knowing it feeds data to three others, the downstream failures are predictable in hindsight but invisible without dependency mapping. This practice prevents collateral damage from changes and accelerates root cause analysis.
