Six qualities are crucial for evaluating theories—- scope, parsimony, heuristic value, openness, appropriateness, and validity . As you recall, scope refers to the breadth of the theory, parsimony to its level of simplicity, and heuristic value is the theory’s ability to generate other theories.
What is theory evaluation?
Theory based evaluation is an approach to evaluation (i.e., a conceptual analytical model) and not a specific method or technique. It is a way of structuring and undertaking analysis in an evaluation. A theory of change explains how an intervention is expected to produce its results.
