A press-in method includes a gripping step, a position measurement step of measuring a position of a pile in an objective coordinate system by a measurement management device disposed apart from a press-in machine, a command generation step of generating a command related to an operation of the press-in machine for moving the pile to a target position by using first position information of the pile in the objective coordinate system measured in the position measurement step and second position information on a position of the chuck in a subjective coordinate system based on an advancing direction of a saddle of the press-in machine, a positioning step of moving the pile to the target position, and a press-in step of pressing the pile into a ground.
