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 and 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 and unexpected conditions
alike – required more than the prevention of incidents and
accidents. This developed into a new interpretation of safety
(Safety-II) and consequently a new form of safety management.

Safety-II changes safety management from protective safety and a
focus on how things can go wrong, to productive safety and a
focus on how things can and do go well. For Safety-II, the aim is
not just the elimination of hazards and the prevention of
failures and malfunctions but also how best to develop an
organisation’s potentials for resilient performance – the way it
responds, monitors, learns, and anticipates. That requires models
and 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 and how it can be used to
develop the resilience potentials. The RAG provides four sets of
diagnostic and formative questions that can be tailored to any
organisation. The questions are based on the principles of
resilience engineering and backed by practical experience from
several domains.

Safety-II in Practice is for both the safety professional
and academic reader. For the professional, it presents a
workable method (RAG) for the management of Safety-II, with a
proven track record. For academic and student readers, the book
is a concise and practical presentation of resilience
