Service 01
A practical reconciliation of source, coverage, instrument definition and impact on downstream analysis.
Use this review before replacing a vendor, combining feeds, migrating a normalized store or relying on a new source for a production decision. It is useful when two outputs look comparable but their coverage, session logic or instrument definitions may differ.
Typical sponsors are data, research, platform or product leads. The starting materials are sample extracts or approved access, data dictionaries, current mapping rules, expected use cases and the decision that depends on the comparison.
The review agrees a comparison schema, preserves every match state, tests representative edge cases and returns a written record. The deliverables are a scope, field map, evidence log, defect register, unmatched taxonomy and regression-control recommendation.
This is not a vendor certification, trading recommendation or blanket data-quality warranty. It does not publish licensed source records or reduce a migration to a single headline rate.
Working principle
A written scope, comparison schema, evidence log, unmatched taxonomy, defect map and regression-control recommendation. The next step is a repair or monitoring plan only where the evidence supports it.
