In this paper, we discuss efforts to enhance customer value by reducing customers' life cycle costs (LCC) of construction and mining equipment. Though it is necessary to quantitatively grasp the LCC for the reduction of it, many uncertainties included in LCC of construction and mining equipment have made it difficult. In order to solve this problem, the uncertainties were classified into two types. Then we proposed countermeasures required for three types and showed their effectiveness. The first is to quantitatively measure machine operation data by telematics services and to visualize how it is used. The second is to take countermeasures by the telematics information to maintain the machine conditions. By carrying out the first and second countermeasures by telematics services, accurate simulations of future LCC of these two types of uncertainties become possible. The third is fundamental removal of factors that are accidental and uncontrollable. This was demonstrated by the reduction of accident risks of the autonomous haulage system for mining. By combining the three countermeasures, uncertainties in LCC can be reduced. That makes appropriate LCC reduction countermeasures possible and creates customer value, which is obtaining benefits with less cost.
