Abstract: A first process acquires a true value of the position of a predetermined portion. A second process acquires a reference position of a work machine. A third process determines a plurality of correction candidate values of a parameter. The correction candidate values are used so that a calculation value of the position of the predetermined portion calculated based on the parameter from the reference position matches the true value. A fourth process calculates an assessment value indicative of the difference between the true value and a calculation value for each of plurality of correction candidate values. A fifth process determines a confirmation correction value of the parameter from among the plurality of correction candidate values based on the assessment value.
