Impactful utilization required a focus on outcomes: did it achieve the good that was sought to be achieved by the legislation? In general, that would require demand-side studies to see if people had been brought out of poverty, whether employment had been created, etc..
But before one gets to outcomes, it's necessary to have outputs. If the fund has not resulted in the rollout of networks or whatever it was supposed to support, there is not much point in looking for evidence of outcomes, good or bad.
