In the present invention, a controller determines a first pass target excavation depth on the basis of the end position for the excavation, the target soil volume, and the excavation distance. The controller executes a first pass excavation by moving a work machine to the first pass target excavation depth. The controller acquires the actual volume of soil excavated in the first pass. The controller corrects the target soil volume on the basis of the actual volume of soil. The controller determines a second pass target excavation depth on the basis of the corrected target soil volume. The controller executes a second pass excavation by moving the work machine to the second pass target excavation depth.
