There’s design besides the design.
A well-designed product isn’t well designed if the process needed to manufacture it is unrealistic or uneconomical. A brilliantly conceived alternative-fuel vehicle will not succeed without the design and implementation of a refueling infrastructure over a large geographic area. A cleverly resolved construction detail isn’t clever if it doesn’t leave room for a construction worker to manipulate the tools needed to construct it. A bridge pier that’s well engineered won’t be built without also engineering a process to excavate earth and pour concrete in the middle of a river.
