Abstract
In a project that realizes large-scale systems, such as space systems, it is very important to transmit design information among each system level because the system structure is complicated. Especially in a high-context culture like Japan's, it is very important not only that they transmit the requirement through documents, but also that they share the value and define the metrics in the design trade-off. On the other hand, there are some possibilities when the intervention by a higher-level engineer into lower design activities causes a barrier to effective design activities because there is a kind of principal-agent relationship by asymmetric information concerning the value and the design technology between higher- and lower-level engineers. In this paper we visualize the value transmission and utilization mechanisms of system development, consider the impact of value transmission on the design process theoretically and by simulations, and propose an effective method of value transmission.
