Performance indicators are essential management tools for measuring the performance of a workplace health and safety system. For effective measurement of performance, the system should use both lead and lag indicators, but with a greater weighting on lead indicators.
Lead indicators are important because they measure activities designed to prevent harm, and manage and reduce risk. They are focused on future safety performance.
Lag indicators, on the other hand, measure past performance results and indicate facts about past events. They indicate progress toward compliance with health and safety legislation and regulations.
