A component product or products can be used to make other finished products. For example, a product like wheels can be used to make different types of bicycle products - 20 inch wheels could be used to make a men's bicycle product or a woman's bicycle product. Also a combination of products could be used to make a product. For example the combination of 20 spokes, one 20 inch rim, one inner tube, and one outer tube can be combined to make a 20 inch wheel. Some products are not used to make other products. For example, a finished bicycle isn't used to make any other product. We even have some products that are not made of other products. For example, the bicycle wheel spokes are purchased and not composed of other parts.
