In general, there is a difference between the contract costs and the adjustment stage, and there is a relationship between the adjustment cost and the contract period. In this study, it was found that there is no difference between the contract costs and the adjustment stage within a specific range in terms of the contract period. Therefore, the sample data were divided into three groups based on the contract period, and the difference was determined for each group. It was found from the study results that one group can enter into a firm contract because of the minimal difference between the contract costs and the adjustment stage. An alternative way of entering into a firm contract is thus suggested, using the contract period for the research and development process in the military.
