Abstract

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.

Claims

1. A method comprising:

receiving from an apparatus, an identification of a failed part within said apparatus, by a computing device in communication with said apparatus;

determining, by said computing device, if said failed part failed prematurely by evaluating whether said failed part failed within one of a plurality of predetermined threshold usage ranges;

if said failed part failed prematurely, cross referencing a service recommendation table to identify a service recommendation based on which of said predetermined threshold usage ranges said failed part failed within, using said computing device; and

outputting, from said computing device, instructions to service said failed part and said service recommendation.

2. The method according to claim 1, said plurality of predetermined threshold ranges comprising less than a predicted full useful life of said failed part.

3. The method according to claim 1, said plurality of predetermined threshold ranges comprising different for different parts of said apparatus.

4. The method according to claim 1, further comprising maintaining said service recommendation table based on historical service records of apparatuses similar to said apparatus.

5. The method according to claim 1, said determining of whether said failed part failed prematurely comprising using said computing device to:

extract usage data from a usage meter within at least one of said apparatus and said failed part; and

compare said usage data to said predetermined threshold usage ranges to identify which of said predetermined threshold usage ranges said failed part failed within.
