Practical information and fictional examples for scoping, not claims of client work, measured results, independent assurance or certification.
Name the business consequence
A “quality problem” matters because it changes a decision, causes repeated work or creates an avoidable exposure. Describe the exact workflow and consequence. A duplicate in a marketing export may mean something different from a duplicate in invoicing. Do not assume that a single company-wide accuracy score would help either owner.
Define the population and rule
A usable rule states the asset and field, unit of count, reporting period, exclusions, expected condition and tolerance. Example: in an agreed monthly billing population, each approved invoice should have one unique invoice identifier. The percentage of records that meet that condition is meaningful only with a stated denominator and treatment of missing and excluded records.
Decide what a failure means
Some failed checks require immediate containment; others trigger review before the next report. Specify who investigates, who can accept an exception, what supporting evidence is needed, and whether a report may still be used with disclosure. A threshold should be derived from business consequence and agreed tolerance, not selected because 99% looks impressive.
Test and re-evaluate
Use authorised sample records and deliberately include edge cases: late arrivals, backdated corrections, merged accounts, empty values and source outages. Record test results and dependencies. Re-run after relevant source changes and document any approved rule-version changes. The rule is only operational when someone follows up on failures and knows when to escalate.
What buyers usually ask
Should the target always be 100%?
No. Tolerance should match the business purpose, with explicit exceptions and their consequences.
Does a passed rule certify the report?
No. It supports a scoped assertion about a defined population.
Start with one decision, not a platform purchase.
