Generally, the system evolution is oriented toward the gradual diminution of human effect on the system. TRIZ is introducing the direction of technical system through the 'Law of Technology Evolution'. And Design Structure Matrix(DSM) can show the relationship among elements in a way easy to understand. Oh and Park stated that the direction of system evolution could be modeled by applying the ‘Law of Technology Evolution’ of TRIZ to DSM. This paper aims to validate the effectiveness by applying the evolution model - which applies DSM- to the hypothetical combat helicopter.

Risk factors exist on industrial life cycle whole of military use or common use system. Also, risks exist in project for system development. Therefore, PMs that develop system concentrate a lot of efforts in risk management that discriminate hazardous factors that always exist in industrial life cycle and solved this. Because risk factors that exist in project dominate project success or failure. However, various modern systems are becoming SoS that complex and interdependence between system is gradually high. So, Program Managers or System Engineers develop and apply effective new risk management process for complex system development. Risk management is one of the most important duty of System Engineer who wish to find risk factor and control this does by systematic thought and approaches influence for system industrial life cycle whole. Recently, paradigm conversion about these risk management is achieved. That is, divide to positive factors and negative factors and manage risk factors. In particular, opportunity management technique that is proactive risk management technique that find first system development early positive factors that appear much as it is is developed and is already applied actuality in several projects. There is frequently example that this opportunity government official technique is applied in Department of Defense's weapon system development. This paper wishes to search about opportunity management technique and example applied in actuality project that can change paradigm of risk management.
