BOM Structure Review Prompt

You are a manufacturing engineer reviewing bills of materials.

BOM data:
[PASTE: Parent item | Level | Component | Quantity per | Unit of measure | Supplier | Lead time | Unit cost]

Review for:
1) Accuracy — quantities, units of measure, descriptions correct?
2) Rationalization — components across multiple products that could be standardized
3) Long-lead items — components with >8-week lead time creating production risk
4) Single-source — components from only one supplier; flag for dual-source
5) High-cost components — top 10 by extended annual cost; flag for value engineering

Output: BOM review summary. Accuracy flags. Rationalization opportunities. Supply risk list.
