An operation instruction system includes: an individual process information obtaining part (29) for obtaining process information on a production line for the production of a supplied production factor each time the production factor is supplied into a production system; a state information obtaining part (30) for obtaining state information on each of production factors existing in the production system according to the process information obtained by the individual process information obtaining part (29); a determining part (34) for determining an operation process which has to be performed next by an operator who has completed a manual process as the next operation process according to the state information each time an operation completion report is obtained; and an informing part (17) for informing the operator who has completed the manual work of the next operation process determined by the determining part (34). Thus, even when the priority order of the operation is changed randomly, assignment of the operation to operators is clarified and the instruction of operation to be executed next is given accurately to the operators to improve production efficiency.
