A system and method to assess a serviceability of a machine having a field replaceable unit (FRU) is provided. A controller can perform the steps of tracking performance parameters of the machine; calculating and comparing a performance index; generating requests for service of the FRU of the machine based on the performance index, the requests for service not including replacement of the FRU; detecting completion of a events to service the FRU of the machine; calculating an asset healability index representative of a trend in the performance index over time between each of the events to service the FRU; and generating a request for replacement of the FRU instead of another request to service the FRU based on a comparison of the asset healability index relative to a second predetermined threshold.
