# Impact Analysis

> See downstream blast radius before you ship a change.

## Overview

**Impact analysis** walks the lineage graph forward from a proposed change - a column rename, a dropped table, a dbt model refactor - and surfaces every downstream job, dataset, dashboard, and dollar of recurring spend that would be affected.

Wire impact analysis into your PR flow via the GitHub integration to see blast radius before merge.
