PERFORMANCEINDICATORS
The global process guarantees the system’s coherency by managing the loop.
In the global process an important role is played by the Performance Indicators that shall support the Operator in measuring and monitoring the implementation of environmental and safety policieson a regular basis in order to plan the achievement of safety objectives.
