A renewable-energy firm is sourcing a redesigned battery casing from a supplier that has produced prototypes successfully but has not yet manufactured the casing at commercial volume. The buyer expects early production data to reveal whether labour hours, scrap rates, and material usage are close to the estimates. The supplier is willing to commit capacity, but it does not want the first price to become permanent if production conditions differ materially from the assumptions. Which contract approach best fits this situation?
