Data & preparation
Using provenance in broker comparisons — Compare Data Brokers
ANSWER IN BRIEF
Give candidates the same account of dataset origins and transformations. Compare the evidence they request and the limits they attach to their proposals, while keeping provenance history distinct from approval to license the material.
Prepare a common source account
Describe the original systems and business processes, including imported or third-party material. Identify which team can explain the records. Keep the account understandable without exposing confidential examples. Candidates should receive the same baseline history so a difference in their proposal does not simply reflect an omitted source or an unclear origin story.
List transformations consistently
Record extraction, merging, filtering, redaction and annotation, with the relevant dataset version. Explain what information was removed and which relationships were preserved. Use the same transformation summary across comparisons. A candidate may reasonably request further detail, but its additional assumptions should be recorded rather than silently incorporated into only one version of the brief.
- Share one source and transformation summary.
- Link each request to a qualification question.
- Record unresolved gaps and assumed answers.
Compare the actual evidence requests
Ask which provenance questions affect qualification and why. Distinguish requests needed to understand the dataset from requests about permission or commercial scope. A longer questionnaire is not automatically a stronger process. Compare whether the questions resolve material uncertainties and whether the company can supply proportionate evidence through an approved channel.
Track unanswered questions
Record who owns each gap and what a candidate assumes while it remains unresolved. Do not treat an absence of questions as confirmation that every source is acceptable. Use a shared evidence log to communicate corrections. The comparison should retain the source history and limits behind each conclusion about the proposed opportunity.
Questions & answers
What makes this comparison useful?
The same starting scope, a recorded source for each material statement, and a clear account of differences or unknowns that could change the company’s decision.
