A system and method for monitoring the performance of at least one machine operator, the system comprising at least one measuring device for measuring at least one machine parameter during operation of the machine by the operator, a server (8) for generating at least one performance indicator distribution from measurements of the at least one machine parameter and a performance indicator calculation module (18) for calculating at least one performance indicator from the at least one performance indicator distribution. Feedback may be provided to the operator by displaying the at least one performance indicator in substantially real-time to the operator on display module (6) onboard the machine.
