While critical control frameworks are becoming increasingly common in mines and quarries in NSW, effective implementation of these frameworks can be hampered by an inadequate grasp of the necessary data inputs, indicators and human psychology that govern whether the framework will create the intended outcome. As statutory mechanical officials in mines and quarries in NSW, assuring the effectiveness of critical risk controls can significantly reduce blidspots and improve your ability to know where you stand in relation to critical control effectiveness. This presentation will elevate your ability to: • Identify and address complexity risk in developing critical control frameworks • Recognise and respond to cognitive bias to maximise the performance of critical control frameworks • Evaluate and apply key risk indicators and risk tolerances in order to effectively and honestly measure the performance of critical control frameworks.
