This book is a simulation of a live course on human performance improvement/human error prevention (HPI/HEP) created by the preeminent authority on HPI/HEP. It presents the greatest breadth of scope and specificity on this topic. This book comprises a focused, challenging human error prevention training course designed to improve understanding of error causation. It will dramatically reduce human error and repeat deviations, and it digs below the surface of issues and looks to fix the real causes of human error and mistakes. In addition, this book presents a complete seminar from the thought leader acclaimed by hundreds of clients, and includes unique principles, practices, models, and templates. Information is comprehensive and can be directly implemented. The principles and practices of human error prevention are universally applicable regardless of the type of industrial, commercial, or governmental enterprise, and regardless of the type of function performed within the enterprise. The application of the information in this book will significantly contribute to improved productivity, safety, and quality. After fully using this book, you will understand: Human error prevention/reduction terminology and definitions. The relationships among culture, beliefs, values, attitudes, behavior, results, and performance. The roles of leadership in establishing and maintaining a quality/safety-conscious work environment.
