Since 1984 Behavior-Based Safety (BBS) has proven to be an effective tool for the reduction of workplace accidents. While the business climate has changed dramatically since 1984, Behavior-Based Safety has changed little. Even a proven technology or any pre-defined methodology with documented results eventually must evolve or become obsolete. Lean Behavior-Based Safety (Lean BBS) is an enhanced approach and improvement to traditional Behavior-Based Safety, utilizing aspects of performance and quality systems to drastically reduce the typical internal resource requirements of a Behavior-Based Safety process. Lean Behavior-Based Safety focuses on leveraged (efficient and effective) use of resources. This leaner model is as easy to implement and provides greater and faster return than the resource-intensive, wait and see approaches. Every methodology that produces results must continue to evolve or it will fail to produce new value
