How we verify every statistic
Every figure on Manufacturing Metrics passes a four-stage pipeline before publication.
Primary-source collection
Figures come only from peer-reviewed work, government statistics and named industry reports — never unsourced blogs.
Editorial curation
An analyst records every figure's source and date and discards anything that cannot be traced.
Independent verification
Each statistic is reproduced from the original source and cross-checked against a second where one exists.
Senior sign-off
Only verified figures are published, tagged Verified, Directional or Single-source.
Confidence labels
Verified — reproducible from two or more independent primary sources. Directional — sources agree on direction and magnitude but not the exact value. Single-source — one primary source, not yet corroborated.
Software rankings follow the same discipline: one uniform rubric (Metric breadth 40% · Integrations 35% · Ease of use 25%), applied identically to every vendor. See How we make money.
