when starting the design of a new vehicle, after understanding the target buyer's desire and the overall market, what should come next? (a) A conceptual business case should be developed to identify initial cost, investment as well as production capacity targets. (b) initial major vehicle system decisions should be made to enable design work to start. In particular, key architectural decisions such as Powertrain and Vehicle Platform systems should be decided early. (c) Manufacturing decisions should be made so that the facilities that will be building the vehicle can be engaged in the design effort to assure best quality and to start identifying key strategic supplier partners that will be engaged in the design of vehicle subsystems. (d) vehicle styling should be started so that product market research can determine product demand. Virtual and physical models of the vehicle are needed when dealing with buyers since they struggle to understand or relate to abstract descriptions without a tangible artifact that captures the vision for the program
