The importance of systems relationships from a risk control and fleet safety management perspective is that The importance of systems relationships from a risk control and fleet safety management perspective is that When a smaller system fails, the larger system of which the smaller system is a part is more likely to fail. Failure of any component leads to increased strain on only smaller subsystems. Directing all risk management energy toward smaller systems is most cost effective. Focusing on the larger system, of which the smaller system is a part, will result in the best risk management outcomes
