1. A method of using a computer system to map a first set of configuration rules to a second set of configuration rules, wherein each configuration mapping rule includes a set of parts of a product, the first set of configuration rules includes a first configuration rule and the second set of configuration rules includes a second configuration rule, the method comprising: accessing, from a first memory, multiple, part-to-part mapping rules; combining the multiple, part-to-part mapping rules into a consolidated configuration mapping rule that maps parts in the first configuration rule to parts in the second configuration rule; and storing the consolidated configuration mapping rule in a second memory.
