• For compliance managers, the value of a market size report lies in its transparency and traceability. A reliable report will name its data sources, explain its estimation methods, and clearly distinguish historical data from projections. Red flags include unverifiable statistics, missing methodology, and conclusions that conveniently support a vendor's product.
• Check methodology before numbers—if you can't see how they got the figures, they're not worth your budget.
• Demand source transparency: reliable reports name their primary data providers.
• Distinguish hard data from forecasts—forecasts are educated guesses, not facts.
• Beware reports that mix definitions (e.g., units vs. revenue) without clear labels.
• Use your own cross-checks: compare figures from multiple independent sources.
