A series of processing that includes a first control step for controlling an apparatus that executes predetermined processing and a second control step for controlling the apparatus based on a control result of the first control step is executed. An execution history of the first control step or the second control step is stored in a memory. The series of processing is interrupted in a case where a predetermined interruption factor occurs during execution of the series of processing. In a case where the interruption is executed, a start step for resuming the series of processing is set to the first control step or the second control step, based on the execution history stored in the memory.
