Phase 1 · Deliverable 08 of 10

Number-assurance journey

A leadership KPI looks poor, but the real issue is that it cannot yet be defended. The journey shows how the product keeps "untrusted" apart from "bad", traces the cause through lineage, and returns a human-certified number to the leadership view. It uses the same synthetic world as 07 (Entity A1, Plant 02, Line L2).

E-08 KPI Certification Workbench

Analyst → Administrator → Metric Owner

Analyst attaches evidence (mapping diff, meter log extract [PH]) and requests correction. The Administrator applies the approved mapping fix (no certify control is visible to them). The KPI recomputes to 401.2 kt, and the variance is now within tolerance.

Request correction (Analyst) · execute change (Admin) · confirm definition unchanged (Metric Owner)

Validation Assistant re-checks cross-source consistency: 'Within tolerance; L2 meter calibration evidence missing'

Options: Certify · Certify with exception · Request correction. Rationale is mandatory. Evidence checklist shows the calibration certificate as outstanding.

Cannot certify. The panel shows: 'AI checks are advisory'

P07 flash

Pending certification

Daily flash shown as preliminary; certification due at close.

D-2 → D0

Reconciliation break

Flash vs MIS beyond tolerance after the mapping change.

D0 + correction

Pending certification

Recomputed value within tolerance; awaiting human decision.

D0 decision
