A method and system determine if a failed part failed prematurely by evaluating whether the failed part failed within one of a plurality of predetermined threshold usage ranges. The predetermined threshold ranges are less than a predicted full useful life of the failed part. Therefore, if the part failed within one of the usage ranges it would be considered to have failed before its predicted full useful life and to have failed prematurely. If the failed part failed prematurely, the method cross-references a service recommendation table to identify a service recommendation based on which of the predetermined threshold usage ranges the failed part failed within. The service recommendation table provides different service recommendations for different predetermined threshold usage ranges of different parts. The service recommendations are often recommendations that adjust or replace items other than the failed part itself. Thus, the service recommendations address the root cause that may have caused the part to fail prematurely.
