Production output is up. Lines are running at higher utilisation, new shifts have been added, and on paper the plant looks more efficient than it did a year ago.
Then finance is asked what that growth actually did to true cost-per-unit, and the honest answer takes longer to reach than it should. Scrap, rework, and downtime cost aren't always reconciled consistently against the specific run or line that generated them.
Whether output growth is translating into durable margin, or simply adding volume at a cost leadership hasn't fully priced, isn't something that can currently be answered with confidence.
