From records to
reliable decisions.

A traceable flow from source records to reporting, with reconciliation and visible exceptions.

The problem
to solve.

Records arrive from disconnected systems with different identifiers, timestamps and status labels. Teams reconcile extracts manually, and discrepancies are difficult to trace.

The proposed approach

Map source systems and agree a common record contract. Preserve source identity, event time, amount units, currency, status mappings and the transformation version. Validate the outputs with comparison runs before reporting depends on them.

Decisions that
shape the work.

Preserve provenance

Every output retains the source record, ingestion run and transformation version.

Keep exceptions visible

Missing identities and unknown states enter a review queue. Do not silently discard or reinterpret them.

Make reruns safe

Use stable identifiers and versions so reloading a source does not duplicate the event. Separate event time from ingestion time.

Define what
good looks like.

Proposed acceptance checks. Confirm the actual rules and thresholds with the owner.

Record identity

Source system and stable source identifier are present.

Money representation

Amount units, currency and rounding rules remain explicit.

Reconciliation

Counts and amounts reconcile by source and reporting period.

Late arrivals

The data owner agrees how late events affect prepared periods.

Leave it in
good hands.

Handover

Source register, mapping specification, validation evidence and operating instructions for monitoring, recovery and reruns.

Measurement

Agree freshness, completeness and reconciliation thresholds with the data owner. Compare investigation effort against the original process. No measured client outcome is asserted.
