One method. One scale. Every company, every division.
An evidence-based record of company AI practice.
Every company is measured by the same published method on the same scale. There is no sector-specific scoring and no second scale for companies that take part.
The Index scores 8,000+ companies every month from public evidence. It scores evidenced AI practice from public sources across six drivers: Strategy and ROI, Technology, Data, Production, Governance, People. It does not prove realized return.
Public evidence
Each public source (filings, earnings calls, careers pages, press releases, product pages) becomes a dated record.
Each record is matched to one driver and given points by stage: stated, piloted, in production.
Driver points add up to a score from 0 to 100. The band is the confidence range: fewer independent sources, wider band.
Point values by stage and driver weights: Pending publication [in build]
What counts as evidence, by sector
The six drivers and their weights are the same for every company. What counts as evidence differs by sector and is published here at the same point values. Companies can propose their sector's equivalent through a correction; accepted proposals are added for everyone.
Sector differences show up as score differences; there is no sector-adjusted scoring. Evidence density shows up in the band, not the score.

Three colleagues, one each from business, technology and people, confirm the record. About 15 minutes each.
Answers run 1 to 5 and scale to 0 to 100. "I don't know" is left out, never zero.
Attestation changes the label and narrows the band. It never moves the percentile by itself.
Evidence labels
Built from public sources only. The company has not replied.
Three colleagues confirmed the record. The band is narrower.
Weaver reviewed evidence the company sent against the record.
Reserved. A third party has assured the record. Not yet in use.
Corrections
Originals are never edited. A correction is a new record that points to the old one, with the reason. Both stay visible.
Two clocks
Every record carries when the fact applied and when we learned it.
Methods governance
Changes are announced one month ahead with a changelog.
Methods 1.0 to 1.1 bridging note: Pending publication [in build]
Independence
No payment, license or partnership changes a score.
Partners may help collect evidence; only Weaver reviews and scores, and partner involvement is disclosed on the record.
Weaver offers no consulting or implementation.
The Index publishes statements and evidence. It draws no conclusions about any company.
Correlation to outcomes
We will publish an independent study of whether Index scores relate to later company outcomes. Method first, results after, including a weak result.
No study exists yet. [planned]
