Accident investigation and risk assessment have for decades focused on the human factor, particularly 'human error'. Countless books and papers have been written about how to identify, classify, eliminate, prevent and compensate for it. This bias towards the study of performance failures, leads to a neglect of normal or 'error-free' performance and the assumption that as failures and successes have different origins there is little to be gained from studying them together. Erik Hollnagel believes this assumption is false and that safety cannot be attained only by eliminating risks and failures. The ETTO Principle looks at the common trait of people at work to adjust what they do to match the conditions - to what has happened, to what happens, and to what may happen. It proposes that this efficiency-thoroughness trade-off (ETTO) - usually sacrificing thoroughness for efficiency - is normal. While in some cases the adjustments may lead to adverse outcomes, these are due to the very same processes that produce successes, rather than to errors and malfunctions. The ETTO Principle removes the need for specialised theories and models of failure and 'human error' and offers a viable basis for effective and just approaches to both reactive and proactive safety management.

This innovative book aims to bring the science of safety into a simple and practical approach to investigating workplace incidents. As a basis, it uses the ideas of some of the great safety science thinkers of our time. These include Sidney Dekker, Todd Conklin, Erik Hollnagel, Daniel Kahneman, James Reason and Dylan Evans, alongside others and the author’s own extensive industry experience. Simplicity in Safety Investigations: A Practitioner's Guide to Applying Safety Science will better equip readers to deal with incident investigations by helping them understand the science behind investigation techniques, and by exploring coaching and leadership styles that help them ask better questions both before and after workplace incidents. The first two chapters of the book focus on our mindset as we approach and undertake investigations, and the simple things we all must do before an investigation starts. The third chapter is a step-by-step guide on how to undertake both simple and more detailed workplace incident investigations. Chapter 4 is reserved for a more detailed review and set of explanations around the science and thinking behind the method and approach. This book serves as an easy-to-follow, real-world reference for supervisors, managers and safety practitioners across many industries.

Properly performing health care systems require concepts and methods that match their complexity. Resilience engineering provides that capability. It focuses on a system’s overall ability to sustain required operations under both expected and unexpected conditions rather than on individual features or qualities. This book contains contributions from international experts in health care, organisational studies and patient safety, as well as resilience engineering. Whereas current safety approaches primarily aim to reduce the number of things that go wrong, Resilient Health Care aims to increase the number of things that go right.

Society at large tends to misunderstand what safety is all about. It is not just the absence of harm. When nothing bad happens over a period of time, how do you know you are safe? In reality, safety is what you and your people do moment by moment, day by day to protect assets from harm and to control the hazards inherent in your operations. This is the purpose of risk-based thinking, the key element of the six building blocks of Human and Organizational Performance (H&OP). Generally, H&OP provides a risk-based approach to managing human performance in operations. But, specifically, risk-based thinking enables foresight and flexibility—even when surprised—to do what is necessary to protect assets from harm but also achieve mission success despite ongoing stresses or shocks to the operation. Although you cannot prepare for every adverse scenario, you can be ready for almost anything. When risk-based thinking is integrated into the DNA of an organization’s way of doing business, people will be ready for most unexpected situations. Eventually, safety becomes a core value, not a priority to be negotiated with others depending on circumstances. This book provides a coherent perspective on what executives and line managers within operational environments need to focus on to efficiently and effectively control, learn, and adapt.

The studies reprinted here deal with the Byzantine empire between the 9th and 11th centuries, with a focus on the period of the Macedonian dynasty, and include four translated into English for this volume. They reflect both historical and prosopographical concerns, but Professor Markopoulos's principle interest is in the analysis of literary works and texts. This he combines with the examination of the ideological context of the period, as shaped in the reigns of Basil I and Constantine VII Porphyrogennetos, and the investigation of gender issues and other approaches. The close analysis of the texts shows how, after the close of Iconoclasm, new styles of writing and new attitudes towards the writing of history emerged, for instance in the use of mythological themes, which exemplify the changing intellectual concerns of the time.
