1. A method, comprising: obtaining a laboratory data value for a property of interest of a product using off-line testing in a laboratory environment; obtaining laboratory data values for other properties of the product using off-line testing in the laboratory environment; obtaining measured data values for the other properties of the product using on-line measurement during production of the product; determining, using a laboratory data validation model of a process controller, a predicted value for the property of interest based on the laboratory data values and the measured data values for the other properties of the product; and determining, using the laboratory data validation model of the process controller, validity of the laboratory data value for the property of interest with respect to the predicted value for the property of interest, wherein the validity of the laboratory data value for the property of interest relates to whether the laboratory data value for the property of interest is within an acceptable range around the predicted value for the property of interest.
