PURPOSE:To provide a production management method capable of shortening the manufacture lead time and maintaining the maximum throughput. CONSTITUTION:A reference processing amount, a management limit value, a process restoration margin and a reference completed amount are set for respective processes beforehand and a real processing amount A and the management limit value B are compared every time when a prescribed time elapses (a step 1b). When the process for which the real processing amount A exceeds the management limit value B in the comparison is present, the message for warning is displayed at respective work instruction devices (the steps 1d and 1d') and further, when a completed amount result summed-up total D in the process is less than a reference completed amount summed-up total C, the processing amount is increased by using the process restoration margin. Also, when the completed amount result summed-up total D is more than the reference completed amount summed-up total C, informing for limiting the processing amount of a previous process is performed.
