Automotive Parts Shipment Tracker

At the earliest milestone where the math says the line is at risk: remaining buffer stock (in production-hours) versus realistic remaining transit. Automotive logistics runs premium-freight desks precisely because a $12,000 charter beats a $200,000 line stop. The board's job is making the slip visible while the charter option still exists — which means daily status honesty, not optimistic ETAs.

The constraint encoded in the plant / line need date field: the cost of late isn't storage, it's line-down. Generic trackers show where freight is; cargo-specific tracking shows whether the plan still works for what this freight IS — and that difference is where the expensive mistakes hide.

Whoever learns first — typically the ops person reading carrier notifications — with a single named owner per board so statuses can be trusted. For this cargo the discipline matters doubly: downstream parties (QA, sites, sales) make real commitments off these rows, so 'the board is always current' has to be a rule, not an aspiration.

That's the compounding payoff: a quarter of rows is this lane's real transit and exception record for THIS cargo — far more persuasive than generic carrier stats. Late-rate by carrier, slip distribution, exception causes: export, pivot, and bring it to the QBR. Specific cargo data wins arguments generic benchmarks lose.
