BACKGROUND

In the related art, a maintenance staff of a maintenance target device performs a maintenance work according to a procedure manual that discloses a maintenance procedure and their own rules of thumb. However, the maintenance staff may perform a maintenance work that is different from a correct maintenance work due to misunderstandings or a work mistake. In such a case, the maintenance staff may take a longer period of time than time expected for the maintenance work, or may not be able to finish the maintenance work normally. Therefore, a technology that enables a maintenance work in the correct procedure is required.
