A non-transitory computer-readable storage medium storing a work plan specifying program that causes at least one computer to execute a process, the process comprising:

• specifying a certain order under conditions that, in a work line that includes a cutting device and a working device and generates a plurality of objects in the certain order, a certain amount of a material is partially cut by the cutting device from a raw material for each of the plurality of objects, the cut material is processed by the working device, the raw material is switched to a next raw material when the raw material lacks in the cutting device, settings for one selected from the cutting device and the working device are determined for each of the plurality of objects, and a changeover is performed to change the settings of one selected from the cutting device and the working device when the settings are changed;
• and
• optimizing an objective function that reflects the changeover and an excess amount of each raw material that are determined according to an input order of the plurality of objects to the work line.
