The results of a gap analysis can be used as input for using a formative method of evaluation. Formative evaluation is used as we move toward the end goal of the policy or program being developed. We develop interventions based on closing the gaps.

A cost-benefit analysis can be used as part of the needs assessment to determine if a planned policy or program ought to be pursued, especially from an economic or efficiency perspective.

But, as Jansson (2020) points out we can develop instruments to collect useful data and from there create outcome assessments. These could be as simple as a satisfaction survey, or it could utilize complicated regression analysis. The main thing being that we have reliable ways and me
