DATA GUIDE
Data quality

Useful data starts
with usable evidence.

Check whether records connect, identities remain consistent and outcomes can be inspected. A quality framework should make uncertainty visible.

Six questions to investigate

Make the quality visible.

Do the records connect?

Measure validated links against a defined eligible set. Keep inferred relationships separate.

Do links survive preparation?

Compare authorized before-and-after samples. Explain exclusions and broken relationships.

Are identities consistent?

Check collisions, shared accounts and split identities across systems.

Is the workflow complete?

Inspect requests, decisions, actions and observable results. Label missing steps.

Is there useful context?

Measure deduplicated activity by type and time period, with distributions and exclusions.

Do sources overlap in time?

Confirm date coverage, timestamp meaning and gaps in the shared window.

Quality is not a privacy verdict.

Connected pseudonymous records can still carry identification risk. A complete workflow does not establish permission to share it. Keep rights, privacy and technical fitness as separate review questions.
