Book Synopsis The ETTO Principle: Efficiency-Thoroughness Trade-Off by : Professor Erik Hollnagel
Download or read book The ETTO Principle: Efficiency-Thoroughness Trade-Off written by Professor Erik Hollnagel and published by Ashgate Publishing, Ltd.. This book was released on 2012-10-01 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accident investigation and risk assessment have for decades focused on the human factor, particularly ‘human error’. This bias towards performance failures leads to a neglect of normal performance. It assumes that failures and successes have different origins so 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 alternative is to understand why things go right and to amplify that. The ETTO Principle looks at the common trait of people at work to adjust what they do to match the conditions. It proposes that this efficiency-thoroughness trade-off (ETTO) is normal. While in some cases the adjustments may lead to adverse outcomes, these are due to the same processes that produce successes.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Resilience Engineering by : Professor David D Woods
Download or read book Resilience Engineering written by Professor David D Woods and published by Ashgate Publishing, Ltd.. This book was released on 2012-10-01 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: For Resilience Engineering, 'failure' is the result of the adaptations necessary to cope with the complexity of the real world, rather than a malfunction. Human performance must continually adjust to current conditions and, because resources and time are finite, such adjustments are always approximate. Featuring contributions from leading international figures in human factors and safety, Resilience Engineering provides thought-provoking insights into system safety as an aggregate of its various components - subsystems, software, organizations, human behaviours - and the way in which they interact.
Book Synopsis Safety-I and Safety-II by : Erik Hollnagel
Download or read book Safety-I and Safety-II written by Erik Hollnagel and published by CRC Press. This book was released on 2018-04-17 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety has traditionally been defined as a condition where the number of adverse outcomes was as low as possible (Safety-I). From a Safety-I perspective, the purpose of safety management is to make sure that the number of accidents and incidents is kept as low as possible, or as low as is reasonably practicable. This means that safety management must start from the manifestations of the absence of safety and that - paradoxically - safety is measured by counting the number of cases where it fails rather than by the number of cases where it succeeds. This unavoidably leads to a reactive approach based on responding to what goes wrong or what is identified as a risk - as something that could go wrong. Focusing on what goes right, rather than on what goes wrong, changes the definition of safety from ’avoiding that something goes wrong’ to ’ensuring that everything goes right’. More precisely, Safety-II is the ability to succeed under varying conditions, so that the number of intended and acceptable outcomes is as high as possible. From a Safety-II perspective, the purpose of safety management is to ensure that as much as possible goes right, in the sense that everyday work achieves its objectives. This means that safety is managed by what it achieves (successes, things that go right), and that likewise it is measured by counting the number of cases where things go right. In order to do this, safety management cannot only be reactive, it must also be proactive. But it must be proactive with regard to how actions succeed, to everyday acceptable performance, rather than with regard to how they can fail, as traditional risk analysis does. This book analyses and explains the principles behind both approaches and uses this to consider the past and future of safety management practices. The analysis makes use of common examples and cases from domains such as aviation, nuclear power production, process management and health care. The final chapters explain the theoret
Download or read book The Human Element written by Dik Gregory and published by . This book was released on 2010-04-29 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a wide range of consultations with maritime organisations, the guide was produced by organisational psychologists gs partnership ltd, for consortium partners UK Maritime and Coastguard Agency, BP Shipping, Teekay Marine Services, and the Standard P&I Club. Aimed at everyone in the shipping industry, the Guide explains the fundamental aspects of human behaviour, which together constitute what the commercial maritime sector calls 'the human element'. It makes clear that the human element is neither peripheral nor optional in the pursuit of a profitable and safe shipping industry. The Guide clearly shows that managing the human element must take place simultaneously at all levels of the industry. Analysis of continuing shipping disasters has increasingly implicated the human element. The loss of life, the impact on company profits and credibility, and the vast environmental damage that can result from the loss of even a single vessel remain clear. The Guide offers insight, explanation and advice to help manage the human element more effectively, more safely and more profitably.

Book Synopsis Proceedings of the Fourth Resilience Engineering Symposium by : Erik Hollnagel
Download or read book Proceedings of the Fourth Resilience Engineering Symposium written by Erik Hollnagel and published by Presses des MINES. This book was released on 2013-04-17 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings document the various presentations at the Fourth Resilience Engineering Symposium held on June 8-10, 2011, in Sophia-Antipolis, France. The Symposium gathered participants from five continents and provided them with a forum to exchange experiences and problems, and to learn about Resilience Engineering from the latest scientific achievements to recent practical applications. The First Resilience Engineering Symposium was held in Söderköping, Sweden, on October 25-29 2004. The Second Resilience Engineering Symposium was held in Juan-les-Pins, France, on November 8-10 2006, The Third Resilience Engineering Symposium was held in Juan-les-Pins, France, on October 28-30 2008. Since the first Symposium, resilience engineering has fast become recognised as a valuable complement to the established approaches to safety. Both industry and academia have recognised that resilience engineering offers valuable conceptual and practical basis that can be used to attack the problems of interconnectedness and intractability of complex socio-technical systems. The concepts and principles of resilience engineering have been tested and refined by applications in such fields as air traffic management, offshore production, patient safety, and commercial fishing. Continued work has also made it clear that resilience is neither limited to handling threats and disturbances, nor confined to situations where something can go wrong. Today, resilience is understood as the intrinsic ability of a system to adjust its functioning prior to, during, or following changes and disturbances, so that it can sustain required operations under both expected and unexpected conditions. This definition emphasizes the ability to continue functioning, rather than simply to react and recover from disturbances and the ability to deal with diverse conditions of functioning, expected as well as unexpected. For anyone who is interested in learning more about Resilience Engineering, the books published in the Ashgate Studies in Resilience Engineering provide an excellent starting point. Another sign that Resilience Engineering is coming of age is the establishment of the Resilience Engineering Association. The goal of this association is to provide a forum for coordination and exchange of experiences, by bringing together researchers and professionals working in the Resilience Engineering domain and organisations applying or willing to apply Resilience Engineering principles in their...
Download or read book Trade-Off written by Kevin Maney and published by Currency. This book was released on 2010-08-17 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Fresh and Important New Way to Understand Why We Buy Why did the RAZR ultimately ruin Motorola? Why does Wal-Mart dominate rural and suburban areas but falter in large cities? Why did Starbucks stumble just when it seemed unstoppable? The answer lies in the ever-present tension between fidelity (the quality of a consumer’s experience) and convenience (the ease of getting and paying for a product). In Trade-Off, Kevin Maney shows how these conflicting forces determine the success, or failure, of new products and services in the marketplace. He shows that almost every decision we make as consumers involves a trade-off between fidelity and convenience–between the products we love and the products we need. Rock stars sell out concerts because the experience is high in fidelity-–it can’t be replicated in any other way, and because of that, we are willing to suffer inconvenience for the experience. In contrast, a downloaded MP3 of a song is low in fidelity, but consumers buy music online because it’s superconvenient. Products that are at one extreme or the other–those that are high in fidelity or high in convenience–-tend to be successful. The things that fall into the middle-–products or services that have moderate fidelity and convenience-–fail to win an enthusiastic audience. Using examples from Amazon and Disney to People Express and the invention of the ATM, Maney demonstrates that the most successful companies skew their offerings to either one extreme or the other-–fidelity or convenience-–in shaping products and building brands.
Book Synopsis The Illusion of Risk Control by : Gilles Motet
Download or read book The Illusion of Risk Control written by Gilles Motet and published by Springer. This book was released on 2017-08-01 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book explores the implications of acknowledging uncertainty and black swans for regulation of high-hazard technologies, for stakeholder acceptability of potentially hazardous activities and for risk governance. The conventional approach to risk assessment, which combines the likelihood of an event and the severity of its consequences, is poorly suited to situations where uncertainty and ambiguity are prominent features of the risk landscape. The new definition of risk used by ISO, “the effect of uncertainty on [achievement of] one’s objectives”, recognizes this paradigm change. What lessons can we draw from the management of fire hazards in Edo-era Japan? Are there situations in which increasing uncertainty allows more effective safety management? How should society address the risk of potentially planet-destroying scientific experiments? This book presents insights from leading scholars in different disciplines to challenge current risk governance and safety management practice.

Book Synopsis The Field Guide to Human Error Investigations by : Sidney Dekker
Download or read book The Field Guide to Human Error Investigations written by Sidney Dekker and published by Routledge. This book was released on 2017-11-01 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title was first published in 2002: This field guide assesses two views of human error - the old view, in which human error becomes the cause of an incident or accident, or the new view, in which human error is merely a symptom of deeper trouble within the system. The two parts of this guide concentrate on each view, leading towards an appreciation of the new view, in which human error is the starting point of an investigation, rather than its conclusion. The second part of this guide focuses on the circumstances which unfold around people, which causes their assessments and actions to change accordingly. It shows how to "reverse engineer" human error, which, like any other componant, needs to be put back together in a mishap investigation.
Book Synopsis Resilient Health Care, Volume 3 by : Jeffrey Braithwaite
Download or read book Resilient Health Care, Volume 3 written by Jeffrey Braithwaite and published by CRC Press. This book was released on 2016-10-03 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the 3rd volume in the Resilient Health Care series. Resilient health care is a product of both the policy and managerial efforts to organize, fund and improve services, and the clinical care which is delivered directly to patients. This volume continues the lines of thought in the first two books. Where the first volume provided the rationale and basic concepts of RHC and the second teased out the everyday clinical activities which adjust and vary to create safe care, this book will look more closely at the connections between the sharp and blunt ends. Doing so will break new ground, since the systematic study in patient safety to date with few exceptions has been limited.

Download or read book Foundations of Safety Science written by Sidney Dekker and published by Routledge. This book was released on 2019-04-09 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: How are today’s ‘hearts and minds’ programs linked to a late-19th century definition of human factors as people’s moral and mental deficits? What do Heinrich’s ‘unsafe acts’ from the 1930’s have in common with the Swiss cheese model of the early 1990’s? Why was the reinvention of human factors in the 1940’s such an important event in the development of safety thinking? What makes many of our current systems so complex and impervious to Tayloristic safety interventions? ‘Foundations of Safety Science’ covers the origins of major schools of safety thinking, and traces the heritage and interlinkages of the ideas that make up safety science today. Features Offers a comprehensive overview of the theoretical foundations of safety science Provides balanced treatment of approaches since the early 20th century, showing interlinkages and cross-connections Includes an overview and key points at the beginning of each chapter and study questions at the end to support teaching use Uses an accessible style, using technical language where necessary Concentrates on the philosophical and historical traditions and assumptions that underlie all safety approaches
