Abstract: Even if there are a plurality of items regarding work, a resource of a work trustee can be evaluated, and thus work entrustment is supported. A work entrustment support system includes a storage unit in which resource information in which an item of which work can be performed by a work trustee is correlated with the work trustee is stored, a work sequence generation unit that generates work schedules on the basis of design information, a priority key setting unit that stores information regarding the priority of each of a plurality of items regarding work in the storage unit, a rank value computation unit that evaluates the resource information stored in the storage unit for each of the work schedules generated by the work sequence generation unit on the basis of the information regarding the priority stored by the priority key setting unit, and a display unit that displays a work trustee according to a rank based on evaluation in the rank value computation unit
