A method for producing a desired metal workpiece, wherein the method comprises: - producing an elongate finished material (116; 222) by hot rolling, wherein a first data record is assigned to the finished material (116; 222), wherein the finished material (116; 222) is logically divided in its longitudinal direction into a plurality of first segments, wherein the first data record, for each of the first segments, includes first physical data characterizing the segment; and - working the finished material (116; 222) using a processing process to obtain the desired metal workpiece, wherein the processing process is controlled at least partially on the basis of the first physical data characterizing the first segments that are logically assigned to the finished material (116; 222), wherein a set of manufacturing specifications is provided, wherein each of the manufacturing specifications comprises first physical data of metal workpieces to be produced by the processing process, wherein the control of the processing process comprises: - evaluating, by comparing the first physical data included in the first data record with the first physical data included in the manufacturing specifications, which of the metal workpieces to be produced are producible by the working of the finished material (116; 222) using the processing process; and - selecting the desired metal workpiece among the producible metal workpieces for the working using the processing process, characterised in that - the working of the finished material (116; 222) comprises collecting second physical data of those first segments which are logically assigned to the finished material (116; 222) to be worked, and - the first physical data are checked for plausibility using the second physical data, - on the basis of the plausibility check, measuring systems are optimized, by which the first and/or second physical data were collected, or wherein on the basis of the plausibility check a working of further finished material (116; 222) to be produced by hot rolling is adapted or halted. - producing an elongate finished material (116; 222) by hot rolling, wherein a first data record is assigned to the finished material (116; 222), wherein the finished material (116; 222) is logically divided in its longitudinal direction into a plurality of first segments, wherein the first data record, for each of the first segments, includes first physical data characterizing the segment; and - working the finished material (116; 222) using a processing process to obtain the desired metal workpiece, wherein the processing process is controlled at least partially on the basis of the first physical data characterizing the first segments that are logically assigned to the finished material (116; 222), - evaluating, by comparing the first physical data included in the first data record with the first physical data included in the manufacturing specifications, which of the metal workpieces to be produced are producible by the working of the finished material (116; 222) using the processing process; and - selecting the desired metal workpiece among the producible metal workpieces for the working using the processing process, - the working of the finished material (116; 222) comprises collecting second physical data of those first segments which are logically assigned to the finished material (116; 222) to be worked, and - the first physical data are checked for plausibility using the second physical data, - on the basis of the plausibility check, measuring systems are optimized, by which the first and/or second physical data were collected, or wherein on the basis of the plausibility check a working of further finished material (116; 222) to be produced by hot rolling is adapted or halted.
