What is Engineer-to-Order (ETO)?

• A. Custom-built products designed for the customer
• B. Mass-produced standard products
• C. Assembled from stock components
• D. Made based on forecast

Answer: (A)

Engineer-to-Order means products are designed and engineered to meet a specific customer's requirements before any manufacturing begins. The emphasis is on a unique, customized design, often involving substantial engineering work, project planning, and collaboration with the customer. Because of this, lead times are longer, the bill of materials is built around the custom design, and production cannot proceed until the engineering is approved. This approach is common for highly customized, high-value equipment such as industrial plants, ships, aerospace components, or specialized machinery. It differs from mass-produced standard products, which are designed to be manufactured in large quantities with little to no customization; from items assembled from stock components, which use available standard parts to assemble a product; and from products made based on forecast, which are planned and produced based on predicted demand rather than a specific customer's design.
