Method for evaluating a production process, where at least one production step is carried out on not less than one product, wherein - a measuring device carries out a measurement to calculate information, wherein the information depends on a feature of the product at a measuring point on the surface of the product at the time of the measurement, - the information is generated from the result of the measurement, - an evaluation unit allocates the information to a single grid cell of a first grid designed with just a single grid cell or a grid cell of a first grid consisting of at least two grid cells, wherein one grid cell each of the first grid is each allocated to a surface area of the product, and the evaluation unit allocates the information to the grid cell of the first grid, on the surface area of which the measuring point lies, - the evaluation unit stores the information and/or secondary information depending on said information and position information, which reflects the position of the grid cell of the first grid to which the information was allocated, within the first grid in a databank, characterised in that - the evaluation unit allocates the information to one grid cell of a second grid consisting of a number of grid cells, wherein the number of grid cells of the second grid is greater than the number of grid cells of the first grid, and one grid cell each of the second grid is each allocated to a surface area of the product that is smaller than the surface area to which a grid cell of the first grid is allocated, and the evaluation unit allocates information to the grid cell of the second grid within the surface area of which the measuring point lies, - the evaluation unit stores the information and/or secondary information depending on said information and position information, which reflects the position of the grid cell of the second grid to which the information was allocated, within the second grid in a databank. - a measuring device carries out a measurement to calculate information, wherein the information depends on a feature of the product at a measuring point on the surface of the product at the time of the measurement, - the information is generated from the result of the measurement, - an evaluation unit allocates the information to a single grid cell of a first grid designed with just a single grid cell or a grid cell of a first grid consisting of at least two grid cells, wherein one grid cell each of the first grid is each allocated to a surface area of the product, and the evaluation unit allocates the information to the grid cell of the first grid, on the surface area of which the measuring point lies, - the evaluation unit stores the information and/or secondary information depending on said information and position information, which reflects the position of the grid cell of the first grid to which the information was allocated, within the first grid in a databank, characterised in that - the evaluation unit allocates the information to one grid cell of a second grid consisting of a number of grid cells, wherein the number of grid cells of the second grid is greater than the number of grid cells of the first grid, and one grid cell each of the second grid is each allocated to a surface area of the product that is smaller than the surface area to which a grid cell of the first grid is allocated, and the evaluation unit allocates information to the grid cell of the second grid within the surface area of which the measuring point lies, - the evaluation unit stores the information and/or secondary information depending on said information and position information, which reflects the position of the grid cell of the second grid to which the information was allocated, within the second grid in a databank.
