A Fleet Operations Subsystem (FOS) can determine a machine status such as Parked, Idle, Working, Travel or Turning. The FOS can be configured to determine machine performance by determining the amount of time spent in each status. The performance can be compared to predetermined performance standards, for example a minimum number of hours spent working, or a maximum number of hours spent idle. A performance score can be generated based on the comparison. A report of the performance evaluation can be provided. A report can be in the form of a performance marker graphic on a visual display. The performance marker can represent the performance score. The performance marker can be in the form of an alarm symbol for a poorly performing machine. The system provides an operator or manager the opportunity to improve machine performance.
