A mounter for a manufacturing management method suppresses an occurrence of inventory shortage or excess inventory as much as possible, and provides energy savings when manufacturing is not performed at full capacity. A throughput determining step acquires manufacturing information included in a manufacturing plan while manufacturing equipment is manufacturing mounted boards and determines a throughput of the manufacturing equipment for the mounted boards based on the manufacturing information while the manufacturing equipment is manufacturing a sequence of the mounted boards. A manufacturing condition determining step determines a manufacturing condition for decreasing power consumption of the manufacturing equipment within a range of throughput not lower than the determined throughput in the case where the throughput determined in the throughput determining step is equal to or lower than a current throughput of the manufacturing equipment.
