The multi-product process chart brings all items together on one sheet of paper so they can be pictured easily. It lists, down the left side of a sheet, the operations through which the various items pass. Across the top, side by side and each in a separate column are listed the various products or items involved. The routing of each item is then traced through the required operations. By charting the routings side by side, a ready made comparison, item by item of the flow paths for each can be made.
