A system for outputting a work instruction, in which an image processing device that takes a picture of a photographic subject is connected to an output device is disclosed. The system includes an imaging unit that generates image data showing the picture of the photographic subject; an obtaining unit that obtains determination data used for determining whether a work process performed on the photographic subject is completed; an input unit that inputs reference material data indicating reference materials used for reference in the work process; a determination unit that determines whether the work process performed on the photographic subject is completed, the determination being made depending on whether the photographic subject in the image data is in a state indicated by the determination data; and an output unit that outputs, to the output device, reference material data for a work process specified in accordance with the determination.

Tracing forged parts over their production process includes: capturing process parameters of a forging process; marking a workpiece with a first identifier; storing the captured process parameters and the first identifier in a database; reading the identifier from the workpiece produced in the previous process step; capturing process parameters during subsequent process steps; storing the process parameters of the subsequent process steps in the database for the read identifier, if legibility of the first identifier of the workpiece remains during the subsequent process step; marking the workpiece produced in the subsequent process step with a further identifier, if legibility of the first identifier of the workpiece does not remain during the subsequent process step of the production process; and storing the process parameters of the subsequent process step together with the further identifier and process parameters of the previous process steps and the first identifier in the database.
