The purpose of this study is to clarify contribution of the engineer to eliminate "the challenge which was not assumed in planning and development phase" which is a big barrier in practical phase of CoPS (Complex Products and Systems). If the subject of a development project which performed the technological development differs from the enterprising body in practical phase, the interface or interdependency which have not been recognized may appear in the practical phase. This study focus on such CoPS implementation process that starts with a national project and goes to mass marketing. The qualitative study is conducted by extracting a main organized activity and another horizontal individual activity which complements the main activity and clarifying characteristic of each activity in planning, development, and practical phase. The findings are as follows: In the planning and the development phase, the complementary activity which complements the main activity had occurred inside the formal organization. In the practical phase, the complementary activity occurred "outside" the formal organization (the chain of development with no linkage). It was promoted by highly specialized engineers’ own routine. These results indicate that highly specialized "outside" engineers are required in practical phase of CoPS.
