Board assurance report — production resilience
Quarter to 2026-03-17 · prepared for Board Risk and Audit Committee · AutoResilience Command, rules res-2026.04.1, rate card rate-2026.02, dataset as of 2026-03-17 · exposure direction: Deteriorating
- 154 critical part–line dependencies are modelled across 3 plants and 4 vehicle programmes.
- 113 sit below the approved disruption-tolerance target (Operating committee, approved 2026-01-19).
- A disruption at Kessler Wire Systems lasting more than 15.1 hours would stop Synthetic Saltillo Assembly — Chassis Sub-assembly. The line builds Synthetic Pickup Program at $2,112,000 of revenue per hour and the part has no recorded alternate source.
- A disruption at Ostrander Brake lasting more than 16.8 hours would stop Synthetic SC Assembly — Line SC-1 (body). The line builds Synthetic X-Program SX-1 at $1,895,200 of revenue per hour and the part has no recorded alternate source.
- A disruption at Aurelia Interiors lasting more than 16 hours would stop Synthetic SC Assembly — Line SC-2 (final assembly). The line builds Synthetic X-Program SX-1 at $1,812,800 of revenue per hour and the part has no recorded alternate source.
- Direction this period: deteriorating — 101 critical dependencies lost tolerance and 40 gained tolerance against the prior week (weekly resilience snapshot, wms extract, monday 06:00z).
- 63X-1153 at Synthetic SC Assembly — Line SC-2 (final assembly) held 35.9h of verified tolerance. It now holds 16h, against an approved target of 72h. Cause: Consumption drew down usable stock faster than replenishment.
- 83K-1088 at Synthetic SC Assembly — Line SC-1 (body) held 47.8h of verified tolerance. It now holds 16.8h, against an approved target of 72h. Cause: 359 units moved into quarantine and are excluded from usable cover.
- 28E-1134 at Synthetic SC Assembly — Line SC-2 (final assembly) held 45.7h of verified tolerance. It now holds 17h, against an approved target of 72h. Cause: Consumption drew down usable stock faster than replenishment.
- 18B-1001 at Synthetic SC Assembly — Line SC-2 (final assembly) held 37.7h of verified tolerance. It now holds 17.5h, against an approved target of 72h. Cause: Consumption drew down usable stock faster than replenishment.
- Single-source supplier: Ostrander Brake — 83K-1088 (Shock tower D). Affected: Synthetic SC Assembly — Line SC-1 (body), Synthetic X-Program SX-1. Missing protection: No alternate source and no cross-plant transfer agreement.
- Single-source supplier: Solvay Polymers Group — 13C-1184 (Bracket, seat rear E). Affected: Synthetic SC Assembly — Line SC-1 (body), Synthetic X-Program SX-1. Missing protection: No alternate source and no cross-plant transfer agreement.
- Single-source supplier: Solvay Polymers Group — 28E-1134 (Coolant manifold E). Affected: Synthetic SC Assembly — Line SC-2 (final assembly), Synthetic X-Program SX-1. Missing protection: No alternate source and no cross-plant transfer agreement.
- Single-source supplier: Halbrecht Drivetrain — 18B-1001 (Floor pan reinforcement B). Affected: Synthetic SC Assembly — Line SC-2 (final assembly), Synthetic X-Program SX-1. Missing protection: No alternate source and no cross-plant transfer agreement.
- Single supplier site: Ostrander Brake — Ostrander Brake — Nagoya Plant 1, Nagoya (Japan). Affected: 3 critical part number(s) across the production network. Missing protection: No second manufacturing site for these part numbers.
Resilience investments and management action
Is management acting?
- Recommended investment: Establish an approved transfer of 83K-1088 from Synthetic Saltillo Assembly — Frame Line — $62,000 over 25 days, modelled to move tolerance from 16.8h to 53.6h. Highest modelled benefit based on current verified inputs.
- 7 costed options are on the register, owned by named executives.
- 0 decision(s) are recorded in the decision ledger with the authority, deadline and baseline that applied at approval.
- 5 of 12 recorded capabilities have been exercised, technically tested or operationally validated.
- 5 remain documented or undemonstrated and are therefore not counted as protection in any calculation.
- Halbrecht Drivetrain — recovery of supplier order and shipping systems: Documented. The claim is not demonstrated, so the approved conservative recovery assumption of 72 hours is used instead.
- Kessler Wire Systems — recovery of supplier order and shipping systems: Documented. The claim is not demonstrated, so the approved conservative recovery assumption of 72 hours is used instead.
- Aurelia Interiors — recovery of supplier order and shipping systems: Not current. The claim is not demonstrated, so the approved conservative recovery assumption of 72 hours is used instead.
- SC Assembly body shop bank build-ahead: Documented. The claimed manual capacity is not counted as protection.
- One active disruption is being managed: Meridian Stamping ransomware — ERP and EDI unavailable (INC-2026-0113, severity S1, phase responding).
- No executive decision has been required in the period.
- Halbrecht Drivetrain — recovery of supplier order and shipping systems — documented: Evidence quality weak; last assessment 2025-10-08.
- Kessler Wire Systems — recovery of supplier order and shipping systems — documented: Evidence quality weak; last assessment never recorded.
- Aurelia Interiors — recovery of supplier order and shipping systems — not current: Evidence quality partial; last assessment 2025-10-30.
- SC Assembly body shop bank build-ahead — documented: No test record exists.
- Alternate supply of 40Y-1050 from SUP-019 — not demonstrated: No validation record exists.
- 27A-1000 at Synthetic SC Assembly — No inventory or consumption record for this part–line pair.
- 65I-1008 at Synthetic Saltillo Assembly — No inventory or consumption record for this part–line pair.
- 29U-1046 at Synthetic SC Assembly — No inventory or consumption record for this part–line pair.
- Synthetic SC Assembly — Line SC-2 (final assembly): 16h of tolerance against a 72h target for 63X-1153; residual exposure accepted pending the recommended action.
- Synthetic SC Assembly — Line SC-1 (body): 16.8h of tolerance against a 72h target for 83K-1088; residual exposure accepted pending the recommended action.
- Synthetic SC Assembly — Line SC-1 (body): 16.9h of tolerance against a 72h target for 13C-1184; residual exposure accepted pending the recommended action.
- Synthetic SC Assembly — Line SC-2 (final assembly): 17h of tolerance against a 72h target for 28E-1134; residual exposure accepted pending the recommended action.
- Synthetic SC Assembly — Line SC-2 (final assembly): 17.5h of tolerance against a 72h target for 18B-1001; residual exposure accepted pending the recommended action.
- Residual exposure remains until establish an approved transfer of 83k-1088 from synthetic saltillo assembly — frame line completes (25 days).
