The article breaks 'market design' into three concrete tasks. First is price structure—from factory to end-user, decide each layer's margin and purchase terms during product development, not after production. Second is testing logic—before mass production, validate market acceptance with small orders to reduce the risk of heading the wrong direction. Third is promotion incentive—design why each channel layer should actively push your product; motivation can't rely on relationships or goodwill alone. Together, these three shift you from 'finish product and wait for market response' to 'clarify how the market works first, then decide how to make the product.'
