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