17. A computer readable medium comprising data encoded therein for generating a normalized configuration model, wherein the data comprises code executable by a processor to: generate product configuration instances from one or more product configuration models that include non-normalized feature references; identify non-normalized feature references included in one or more of the product configuration instances; access a mapping file, wherein the mapping file includes a map of specific product feature references to normalized feature references; locate normalized feature references that correlate with non-normalized feature references included in the generated product configuration instances; replace non-normalized feature references with correlating normalized feature references in accordance with the mapping file; and generate a normalized configuration model corresponding to the generated product configuration instances using the normalized feature references replacements, wherein the normalized configuration model is configured for use with a configuration system which presents the normalized feature references to a user of the configuration system to allow the user to configure a product using the normalized feature references.
24. The computer readable medium of claim 17 wherein the product is a vehicle.
