To be competitive in the current world market, one must simultaneously design the product and the system to bringforth, sustain, and retire the product. Since much of the cost is determined during conceptual design, the same capability is necessary for the conceptual design. The value of the architecture of the system to bring forth, sustain, and retire the product is the degree to which it will perform those functions in a valuable, cost effective, and timely manner. The effectiveness and efficiency by which the value of various architectures of the system to bring forth, sustain, and retire the product can be determined is a measure of the system to conceptually design the system to bring forth, sustain, and retire the product, and hence is a measure of the conceptual designability of the system to bring forth, sustain, and retire the product.
Both measures combine to define the conceptual designability of the system.
