When companies adopt Lean methods, they often conduct many "Rapid Improvement Events" also known as "Kaizen Events." Although many of these activities are conducted, and many process improvements are discovered, only a small percentage survive as standard operating procedure for the company operations. This means the time spent on these process improvement activities are "asted because the new methods are not used. The improvement gains are not sustained. In the analytical ABC model of Applied Behavior Analysis, these activities are "Antecedents," which last only a short time. In order to build these new methods into daily habits, Consequences are needed, specifically positive reinforcement. This presentation gives OBM practitioners and healthcare / company managers an ABA "preventive maintenance" methodology for sustaining gains called Process Behavior Maintenance (PBM). Participant learn about three skills for sustaining lean gains. These three skills can be added to their own Leader Standard Work (a concept in Lean / Toyota Production System) for maximum effectiveness.
