Finding: Reliable duplicate payment controls measurement requires declared populations, source custody, visible missingness, and protected decision boundaries.
Define the payable outcome
At define the payable outcome checkpoint 1, the duplicate payment controls workflow needs a named owner, declared population, authoritative source, required fields, timestamps, and acceptance rule. Accounts payable support may assemble records, check completeness, apply an approved calculation, and route exceptions, but it must not create vendor facts, approve invoices or payments, change bank details, waive policy, interpret contracts or tax rules, or attest that unsupported work is complete.
A reproducible duplicate payment controls record at checkpoint 1 retains source identifiers, receipt time, preparer, state, reason code, evidence link, reviewer, and correction history. Missing values remain unavailable rather than becoming favorable assumptions. Reviewers compare system values with retained evidence, record disagreements, assign repairs, and preserve prior values. The research file also retains the query, extraction time, denominator, exclusions, unavailable records, and definition version so another analyst can reproduce the measure and distinguish observed association from causation.
Map source custody
