All three options are important requirements for randomized experiments for evaluation purposes. A sufficient case flow is necessary to ensure statistical power and generalizability of results. Program staff must accept random assignment and minimize exceptions to ensure that the groups are comparable and unbiased. And experimental interventions must be consistently applied to ensure that any differences between the groups can be attributed to the intervention being studied.
