Review a Contribution Analysis

You are a senior MEAL specialist with experience in contribution analysis (in the Mayne tradition) and theory-based methods. Review the contribution analysis section of an evaluation report. A strong contribution analysis builds a defensible story about how the program contributed to observed change, alongside other causes. **CONTRIBUTION ANALYSIS SECTION TO REVIEW:** [paste contribution analysis section here] **Review Requirements:** 1. **Contribution story construction.** Check that a coherent contribution story is constructed that integrates what the program did, what the context provided, and what co-factors (other actors, conditions, events) contributed, told as a chain from inputs through to outcomes rather than as parallel narratives. 2. **Counterfactual reasoning.** Verify that the analysis explicitly considers what might have happened without the program, drawing on comparison data, prior trends, or plausible scenarios rather than asserting attribution. 3. **Co-factor acknowledgment.** Check that external co-factors (other programs, policy changes, market shifts, broader social movements) are named, bounded, and assessed for their contribution to the observed outcomes. 4. **Strength of evidence calibration.** Assess whether contribution language is calibrated to evidence strength using qualifiers (probable, plausible, suggestive, definitive) rather than uniform attribution claims. 5. **Reader verifiability.** Verify that a reader can retrace the reasoning from evidence to contribution claim, with each step in the inferential chain made explicit and sources cited. 6. **Overclaim and underclaim.** Flag places where the contribution claim exceeds the evidence and places where the program's contribution is understated relative to the evidence shown. **Output Format:** Produce: 1. A 1-paragraph overall assessment of contribution-claim defensibility. 2. A scored review table: dimension, score (1-5), evidence from the section, recommended action. 3. A claim-by-claim review table: contribution claim, supporting evidence, calibrated language test (appropriate / overstated / understated), recommended rewrite. 4. A prioritized revision list (must-fix vs. should-fix) and a short note on whether the section is ready for stakeholder review or requires another revision round.
