A computer-implemented method for monitoring an operation performed by a machine having an implement is provided. The method includes determining a fuel consumption rate value of the machine. The method also includes generating a provisional value based at least in part on the fuel consumption rate value for the operation. The method further includes determining one or more thresholds for the operation. The one or more thresholds correspond to a normal fuel consumption rate value of the machine for the operation. The method further includes generating a status indicator, indicative of a score of the operation based at least in part on a comparison of the provisional value and the one or more thresholds.
