When implementing ECOs, which items are typically updated?

• A. Configurations, BOMs, and master data
• B. Only software settings
• C. Only user roles
• D. Only test data

Answer: (A)

Engineering Change Orders drive changes to the product definition and require updating the data that describes how the product is built and used. When implementing ECOs, the updates should cover configurations, the bill of materials, and the master data that defines the product and its components. Updating configurations ensures the system enforces the correct options and configurations for different variants. Updating the BOM aligns the listed components and quantities with the new design so manufacturing and procurement know what to assemble. Updating master data keeps essential product records—such as material details, descriptions, units of measure, and classifications—consistent with the new design across the system. These together ensure the change is reflected everywhere it matters in planning, sourcing, and production. Updates limited to software settings, user roles, or test data do not capture the full product change and would miss the key areas that propagate the ECO through the lifecycle.
