Safety-I is defined as the freedom from unacceptable harm The purpose of traditional safety management is therefore to find ways to ensure this freedom' But as socio-technical systems steadily have become larger & less tractable this has become harder to do Resilience engineering pointed out from the very beginning that resilient performance
- an organisation's ability to function as required under expected & unexpected conditions alike
- required more than the prevention of incidents & accidents This developed into a new interpretation of safety (Safety-II) & consequently a new form of safety management Safety-II changes safety management from protective safety & a focus on how things can go wrong to productive safety & a focus on how things can & do go well For Safety-II the aim is not just the elimination of hazards & the prevention of failures & malfunctions but also how best to develop an organisation's potentials for resilient performance
- the way it responds monitors learns & anticipates That requires models & methods that go beyond the Safety-I toolbox This book introduces a comprehensive approach for the management of Safety-II called the Resilience Assessment Grid (RAG) It explains the principles of the RAG & how it can be used to develop the resilience potentials The RAG provides four sets of diagnostic & formative questions that can be tailored to any organisation The questions are based on the principles of resilience engineering & backed by practical experience from several domains Safety-II in Practice is for both the safety professional & academic reader For the professional it presents a workable method (RAG) for the management of Safety-II with a proven track record For academic & student readers the book is a concise & practical presentation of resilience engineering
