1. A method of monitoring the performance of a plant including devices, control loops and equipment comprising:
- a. performing diagnostics from a device level, to a control loop level and then to an equipment level;
b. converting results of the diagnostics of each of said levels into respective Key Performance Indicators (KPIs);
c. comparing said KPIs with predetermined operating benchmarks for each of the said devices, control loops and equipment;
d. determining, using a comparator, performance levels of each of said devices, loops and equipment based on said comparing; and
e. displaying the performance level as only three levels of performance.
