The study asks whether review of a small early batch surfaces defects or ambiguities that matter to the remaining work. Define the batch boundary, sampling rule, acceptance criteria, and release decision in advance. Avoid selecting only convenient or polished examples after seeing the results.
Record defect type, evidence completeness, instruction question, reviewer decision, correction, and whether the learning changed later items. Compare defect opportunities, not just counts, because a ten-field record and a two-field record do not offer the same exposure.
GAO and NIST support disciplined control and review concepts, while the World Bank emphasizes data quality in decision-making. They do not prescribe a universal sample size, prove that early review improves every workflow, or support claims about a specific provider’s quality.
Limitations include small samples, learning effects, reviewer inconsistency, and changes in the later work mix. The protocol cannot isolate causation without a stronger design. Report the selection rule, missing evidence, disagreement, and operational cost alongside any observed improvement.
