The use of leading indicators is a growing hot topic in occupational and environmental health and safety. The Campbell Institute at the National Safety Council has been studying leading indicators for the past two years to help more organizations take advantage of their predictive power. The Institute defines leading indicators as proactive, preventive, and predictive measures to identify and eliminate risks and hazards in the workplace that can cause incidents and injuries. Consider an indicator as a concept that a company would like to measure, such as “employee engagement.” In contrast, a metric is a way of actually measuring this concept, such as “number of employees leading safety meetings.”
