I Would Sample the Records That Look Almost Correct

Editorial note: This is a first-person professional perspective, not a customer testimonial.

The obvious errors are not the whole test

If I were reviewing a cleanup result, I would not sample only the records with blank fields or obvious formatting problems. Those are useful checks, but they are easy to identify. I would also inspect records that look almost correct: a name with a slight variation, a date in a different timezone, two addresses that may belong to different people, or a status that changed without a matching event.

Almost-correct records are where a tidy rule can create a confident mistake. I would compare the original value, the proposed value, the source evidence and the rule used. I would mark whether the sample supports the rule, exposes an exception, or shows that the question cannot be answered from the available source.

Build a sample with different risks

The sample should include ordinary records, edge cases, duplicates, missing evidence, and records that affect a customer-facing or financial workflow. Record the selection boundary and exclusions. A ten-record review can test whether a definition is understandable; it cannot prove that every record in a large dataset is correct.

I would keep an explicit “not enough evidence” result. That outcome protects the review from turning uncertainty into a forced yes or no. It also creates a useful queue for the owner rather than burying the question in a pass percentage.

Finish with action and limits

Every sample result should end with what happens next: accept the rule, revise it, route an exception, collect a missing source, or stop the proposed change. I would also write what the sample does not establish. A clean field does not prove a customer response, and a matching pattern does not prove that two records refer to the same person.

AI Cleanup Doctor can help organize a redacted sample review and its exception notes. It does not replace privacy judgment, security controls, legal advice, or the business owner’s decision. The strongest report is one that makes both the evidence and its limits easy to inspect.
