Every goal traces to at least one service and one measure with a named owner. Test the weakest measure with its owner before the board sees it.
The footprint you are building traces each goal to its services and measures
Every named goal is one band across three lanes, its owner beside it, the services that realise it in the middle and the measures that prove it on the right, and a goal missing a service or a measure is marked untraced because it has either no delivery mechanism or no proof.
