Engineer to order (ETO)

https://en.wikipedia.org/wiki/Engineer_to_order

Engineer to order is a production approach characterized by:[1]

• 1. Engineering activities need to be added to product lead time.

  2. Upon receipt of a customer order, the order engineering requirements and specifications are not known in detail. There is a substantial amount of design and engineering analysis required.

To speed up delivery time, the adoption of concurrent engineering, integrated product team, and lean product development methodologies are used. The critical path methodology is also essential.

Engineer to order environments must employ a flexible and adaptive, demand-driven approach to the manufacturing process.
