In order to prepare against the unpredictable provocation of nK on NWI, instead of the threat based force enhancement, sufficient capability based force planning is required in consideration to enemy capability, operations environment, and technological development. This thesis proposes a method on how to prioritize the required capabilities of NWI during the process of identifying capabilities and investing on the decided acquisition assets. Ambiguity in deciding the priority is eliminated and detailed planning is possible through instituting relationship of organization, operation and capability, and by designating weight based on the above relationship. This method identify the various operations and required capabilities, classify the order of priority clearly for NWI, when compare to other method of priority decision. Although capability based force planning requires more assets and faces limitations due to budget, this method will provide and efficient decision making procedure through precise prioritization.
