Evidence standard

JFScope Research Methodology

A buyer-side method for separating claims from evidence and translating research into a documented commercial decision.

Method owner: JFScope Research Desk   Last reviewed: July 14, 2026

Five evidence labels

Public record

Registration, filings, notices, standards or other attributable public material.

Supplier statement

A claim supplied by the company that remains a claim until corroborated.

Buyer document

RFQs, quotations, contracts, inspection files or transaction records supplied for review.

Field observation

Dated observations from an approved visit, call, inspection or location check.

Analytical inference

A stated conclusion derived from cited evidence, with assumptions and limits visible.

Research workflow

  1. Define the buyer decision. State what must be approved, compared, delayed, renegotiated or rejected.
  2. Set the evidence scope. Identify sources, access limits, destination-market requirements and the review date.
  3. Collect and label evidence. Keep supplier claims separate from records, documents and observations.
  4. Test inconsistencies. Compare names, addresses, model coverage, dates, beneficiaries, quantities and process claims.
  5. State gaps and confidence. Record what could not be verified and what additional step would reduce uncertainty.
  6. Translate evidence into action. Recommend a buyer decision and the conditions attached to it.

Publication standard

Every durable research page should identify the responsible desk, review or modification date, evidence type, unresolved limitations and related methodology.

Illustrative buyer scenarios must not be presented as named client endorsements. Sponsored visibility must not be presented as verified approval.
