 ### Leveraging the Marquez graph
 
-If data in the `airflowsample` table were to arrive late or become stale (imagine that), you would need to know about all the upstream dependencies in order to diagnose and resolve the issue efficiently.
+When data produced by multiple tools in your data ecosystem arrives late or becomes stale, root-cause analysis is much easier when you know:
+- what jobs and datasets are upstream.
+- what the run status of each upstream job is.
+- how each upstream job has performed recently.
+- whether quality issues have affected upstream datasets.
 
-In the graph, you can click on an upstream job node to see information including:
+In the Marquez lineage graph, you can click on an upstream job node to see information including:
 - the latest run status.
 - the last runtime.
 - the time last started.
