A method for identifying a predetermined state of a manufacturing process by monitoring the process which involves, monitoring a plurality of variables that vary in value during the manufacturing process. The method also involves mapping as points in a hyperspace the values of each variable at a plurality of times, where the hyperspace has a number of dimensions equal to the number of variables and the number of points is equal to the plurality of times. The method also involves identifying that a manufacturing process has reached the predetermined state when one of the points reaches a closed volume in the hyperspace that is located within a predefined distance from a predefined location in the hyperspace.
