Fatigue is a significant contributor to human error across all industry sectors. Fatigued people make mistakes. The required operating states listed below will minimise the potential for fatigue impacts in your business and are presented within a Control Framework (CFw). This framework presents industry validated failure modes and the business inputs which should be in place to prevent a required operating state being compromised. The CFw components are: 

1. Required Operating States (ROS)
2. Credible Failure Modes (CFM)
3. Business Inputs (BI) to Maintain the ROS
