Method for operating a device, computer program product and device for producing a product

A method for operating a device for producing a product, the method comprising:

• capturing at least one quality data record comprising measured values of one or more quality parameters that each correspond to one property of the product;
• capturing at least one associated machine data record comprising actual values of one or more adjustable machine parameters of the device;
• chronologically assigning the quality data record to the machine data record and generating a first data record comprising chronologically-correlated measured values and actual values;
• repeating the preceding steps at least once to generate at least one second data record;
• determining a correlation between the one or more quality parameters and the one or more adjustable machine parameters by comparing the captured first and second data records and creating a control model for the device;
• providing a corresponding target value for at least one of the one or more adjustable machine parameters on the basis of the control model, and proceeding from the corresponding target value of the one or more quality parameters.
