Example of a DAG showing LoE scores via different thicknesses and styles of arrows. A Shows an example of a detailed DAG LoE assignment that illustrates all 4 levels. B Shows a simplified version, used to help facilitate high-level discussions, that merges levels 3 and 4 into “weak” and levels 1 and 2 into “strong”6.
