COMPONENT MANUFACTURING SYSTEM AND COMPONENT MANUFACTURING METHOD

A component manufacturing system (100, 100A) includes a main base (10), a first production base (20) and a second production base (30). The main base (10) designs a common wire harness (B1) and optional wire harnesses (OP). The main base has a first order function of determining the number of common wire harnesses to be produced based on temporary order information and placing an order with the first production base, and a second order function of acquiring order confirmation information (41b) from the customer at a timing closer to a delivery date than the temporary order information and placing an order with the second production base for the completed wire harness based on the confirmation information.
