Several other performance evaluation models in the academic literature also describe performance measurement. What distinguishes performance paradox from these other models is that they tend to restrict their scopes either to explanations for changing performance criteria or to endorsements of maximizing on a specific, defined set of static ...
Theory-driven evaluation (also theory-based evaluation) is an umbrella term for any approach to program evaluation that develops a theory of change and uses it to design, implement, analyze, and interpret findings from an evaluation.
