What are common data quality checks you should perform before releasing an ECO?

• A. Verify only the design drawings are updated.
• B. Check supplier lead times only.
• C. Verify BOM accuracy, routing integrity, material availability, lead times, affected stock, cost estimates, and impact on quality specs.
• D. Ignore any deviations.

Answer: (C)

Before releasing an ECO, you should validate multiple data areas to ensure production can proceed without issues: BOM accuracy, routing integrity, material availability, lead times, affected stock, cost estimates, and impact on quality specs. BOM accuracy ensures the components and quantities match the intended design; routing integrity verifies the correct sequence of operations and work centers; material availability confirms required parts can be obtained when needed; lead times ensure schedules are realistic; affected stock identifies which inventories will be impacted by the change and avoids surprises in stock planning; cost estimates capture the financial impact of the change; and impact on quality specs checks that quality criteria, test methods, and acceptance criteria are still appropriate. Together these checks prevent downstream problems and enable a smooth ECO release. The other options are incomplete because they omit essential manufacturing, supply, or quality considerations, or ignore deviations that could propagate issues.
