In addition to many other auxiliary assembly items and operations, a bookshelf requires one special sub-component W which is itself a sub-assembly of parts X and Y while X itself is also an assembly of part Z with it. These assembly structure and the ordering policies for procurement of the respective parts are shown in the product hierarchy structure with appropriate legend below.
