Ten Questions About Human Error

Ten Questions About Human Error asks the type of questions frequently posed in incident and accident investigations, people's own practice, managerial and organizational settings, policymaking, classrooms, Crew Resource Management Training, and error research. It is one installment in a larger transformation that has begun to identify both deep-rooted constraints and new leverage points of views of human factors and system safety. The ten questions about human error are not just questions about human error as a phenomenon, but also about human factors and system safety as disciplines, and where they stand today. In asking these questions and sketching the answers to them, this book attempts to show where current thinking is limited--where vocabulary, models, ideas, and notions are constraining progress. This volume looks critically at the answers human factors would typically provide and compares/contrasts them with current research insights. Each chapter provides directions for new ideas and models that could perhaps better cope with the complexity of the problems facing human error today. As such, this book can be used as a supplement for a variety of human factors courses.

The old Bad Apple Theory of human error promotes the idea that a system is basically safe, with the exception of a few unreliable people. Breaking new ground beyond its successful predecessor, The Field Guide to Understanding Human Error guides you through the traps and misconceptions of the old view. Sidney Dekker presents the view that human error is an organizational problem, and suggests how to apply new theories to your organization, handling questions about accountability and constructing meaningful countermeasures.

Human error is cited over and over as a cause of incidents and accidents. The result is a widespread perception of a 'human error problem', and solutions are thought to lie in changing the people or their role in the system. For example, we should reduce the human role with more automation, or regiment human behavior by stricter monitoring, rules or procedures. But in practice, things have proved not to be this simple. The label 'human error' is prejudicial and hides much more than it reveals about how a system functions or malfunctions. This book takes you behind the human error label. Divided into five parts, it begins by summarising the most significant research results. Part 2 explores how systems thinking has radically changed our understanding of how accidents occur. Part 3 explains the role of cognitive system factors - bringing knowledge to bear, changing mindset as situations and priorities change, and managing goal conflicts - in operating safely at the sharp end of systems. Part 4 studies how the clumsy use of computer technology can increase the potential for erroneous actions and assessments in many different fields of practice. And Part 5 tells how the hindsight bias always enters into attributions of error, so that what we label human error actually is the result of a social and psychological judgment process by stakeholders in the system in question to focus on only a facet of a set of interacting contributors. If you think you have a human error problem, recognize that the label itself is no explanation and no guide to countermeasures. The potential for constructive change, for progress on safety, lies behind the human error label.

For many years, we considered human errors or mistakes as the cause of mishaps or problems. In the manufacturing industries, human error, under whatever label (procedures not followed, lack of attention, or simply error), was the conclusion of any quality problem investigation. The way we look at the human side of problems has evolved during the past few decades. Now we see human errors as the symptoms of deeper causes. In other words, human errors are consequences, not causes. The basic objective of this book is to provide readers with useful information on theories, methods, and specific techniques that can be applied to control human failure. It is a book of ideas, concepts, and examples from the manufacturing sector. It presents a comprehensive overview of the subject, focusing on the practical application of the subject, specifically on the human side of quality and manufacturing errors. In other words, the primary focus of this book is human failure, including its identification, its causes, and how it can be reasonably controlled or prevented in the manufacturing industry setting. In addition to including a detailed discussion of human error (the inadvertent or involuntary component of human failure), a chapter is devoted to analysis and discussion related to voluntary (intentional) noncompliance. Written in a direct style, using simple industry language with abundant applied examples and practical references, this book's insights on human failure reduction will improve individual, organizational, and social well-being.

The investigation and modelling of aviation accident causation is dominated by linear models. Aviation is, however, a complex system and as such suffers from being artificially manipulated into non-complex models and methods. This book addresses this issue by developing a new approach to investigating aviation accident causation through information networks. These networks centralise communication and the flow of information as key indicators of a system’s health and risk. This holistic approach focuses on the system environment, the activity that takes place within it, the strategies used to conduct this activity, the way in which the constituent parts of the system (both human and non-human) interact and the behaviour required. Each stage of this book identifies and expands upon the potential of the information network approach, maintaining firm focus on the overall health of a system. The book’s new model offers many potential developments and some key areas are studied in this research. Through the centralisation of barriers and information nodes the method can be applied to almost any situation. The application of Bayesian mathematics to historical data populations provides scope for studying error migration and barrier manipulation. The book also provides application of these predictions to a flight simulator study for the purposes of validation. Beyond this it also discusses the applicability of the approach to industry. Through working with a legacy airline the methods discussed are used as the basis for a new and prospective safety management system.

Each year billions of dollars are being spent in the area of nuclear power generation to design, construct, manufacture, operate, and maintain various types of systems around the globe. Many times these systems fail due to safety, reliability, human factors, and human error related problems. The main objective of this book is to combine nuclear power plant safety, reliability, human factors, and human error into a single volume for those individuals that work closely during the nuclear power plant design phase, as well as other phases, thus eliminating the need to consult many different and diverse sources in obtaining the desired information.

Human reliability, error, and human factors in the area of power generation have been receiving increasing attention in recent years. Each year billions of dollars are spent in the area of power generation to design, construct/manufacture, operate, and maintain various types of power systems around the globe, and such systems often fail due to human error. This book compiles various recent results and data into one volume, and eliminates the need to consult many diverse sources to obtain vital information. It enables potential readers to delve deeper into a specific area, providing the source of most of the material presented in references at the end of each chapter. Examples along with solutions are also provided at appropriate places, and there are numerous problems for testing the reader’s comprehension. Chapters cover a broad range of topics, including general methods for performing human reliability and error analysis in power plants, specific human reliability analysis methods for nuclear power plants, human factors in control systems, and human error in power plant maintenance. They are written in such a manner that the potential reader requires no previous knowledge to understand their contents. “Human Reliability, Error, and Human Factors in Power Generation” will prove useful to many individuals, including engineering professionals working in the power generation industry, researchers, instructors, and undergraduate and graduate students in the field of power engineering.
