An exemplary embodiment of the invention concerns a method of manufacturing a window or a door. Different groups of components are defined. These components combine to form a window or door. The components that make up a group are monitored on a viewing screen during movement of those components through a manufacturing or assembly location. Practice of the invention facilitates setting up and identifying standard and custom groups for the Window and Door Industry. These groups include but are not limited to the following items, Glass, IG Units, Muntins, Gas, Frames, Sashes, Windows Lines and Window Styles. Such visual software helps set up a window manufacturing sequence criteria used for processing the various groups. It allows the set up of various multiple sort levels and sort criteria within the Groups.
