From its infancy in the late 1970s and early 1980s until now, behavior-based safety (BBS) has been a source of conflict in the safety profession, among company and union leadership, and even between practitioners. Nonetheless, after 30-plus years of use at companies that run the gamut of industries in dozens of countries around the world, it seems safe to assume that the theory and practice of BBS are here to stay. And since that is the case, this reality begs several questions. What is it about the BBS system that companies, safety professionals and practitioners find appealing? What are the criticisms of BBS and are they valid? How have the proponents of BBS answered them? How is BBS different or better than it was 30 or even 20 years ago? What is its future?
