Your brief
Use fictional figures: A reaches 200 people, impact 1, confidence 80%, effort 2. B reaches 100 people, impact 2, confidence 50%, effort 1. Both use the same period.
Possible draft
Fictional example: two improvements
A scores 80 and B scores 100. B ranks higher mathematically but rests on weaker evidence. Check that evidence and any dependencies before scheduling B first.
