Method of analyzing and optimizing a multistage manufacturing process

A method of analyzing a multistage manufacturing process comprising individual steps in order to achieve predefined product properties, comprising;

• carrying out tuning steps, the type, number and extent of said tuning steps being variable;
• quantitatively recording in an electronic database the individual steps of the manufacturing process which relate to at least one production-specific property;
• quantitatively recording from an individual step of the manufacturing process at least one of its extent, its proportion of the costs, its effect on the product property to be achieved and its composition from subelements, wherein the database contains the logs of a number of runs through the multistage manufacturing process;
• and
• plotting the data contained in the database in a three-dimensional graph, the various runs being plotted on a first axis, the individual steps being plotted on a second axis and the number of individual steps or a similar item of information pertaining to the quantity of individual steps being plotted on a third axis.
