The systems thinking philosophy has become popular in human factors and ergonomics and safety science. These methods are being used to understand and resolve complex societal problems in areas such as transport safety, workplace safety, medication error, disaster management, child abuse, financial crises, terrorism, climate change and public health and wellbeing. This handbook presents practical step-by-step guidance for practitioners and researchers wishing to use these methods to tackle complex problems. Each method includes an example case study which demonstrates how the method can be applied and how the results can be interpreted and translated into practical recommendations.The book presents practical guidance on state-of-the-art systems thinking methods and offers case study applications describing systems thinking methods in novel areas. It explains how to translate the outputs of systems thinking methods in practice and introduces systems thinking with an overview of Human Factors and Ergonomics applications.This book will serve as a great reference for students and engineers in the field of systems engineering, complex systems and the design and development of systems, including ergonomics/human factors and systems engineers, designers, architects, industrial engineers, project management engineers, reliability engineers, risk engineers, software engineers and computer engineers.

'Complex sociotechnical systems' are systems made up of numerous interacting parts, both human and non-human, operating in dynamic, ambiguous and safety critical domains. Cognitive Work Analysis (CWA) is a structured framework specifically developed for considering the development and analysis of these complex socio-technical systems. Unlike many human factors approaches, CWA does not focus on how human-system interaction should proceed (normative modelling) or how human-system interaction currently works (descriptive modelling). Instead, through a focus on constraints, it develops a model of how work can be conducted within a given work domain, without explicitly identifying specific sequences of actions (formative modelling). The framework leads the analyst to consider the environment the task takes place within, and the effect of the imposed constraints on the way work can be conducted. It provides guidance through the process of answering the questions of why the system exists, what activities can be conducted within the domain as well as how these activities can be achieved, and who can perform them. The first part of the book contains a comprehensive description of CWA, introducing it to the uninitiated. It then presents a number of applications in complex military domains to explore and develop the benefits of CWA. Unlike much of the previous literature, particular attention is placed on exploring the CWA framework in its entirety. 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 analysis identifies the constraints governing the system; it is contended that through this holistic understanding of constraints, recommendations can be made for the design of system interaction; increasing the ability of users to cope with unanticipated, unexpected situations. This book discusses the applicability of the approach in system analysis, development and evaluation. It provides process to what was previously a loosely defined framework.

Military command and control is not merely evolving, it is co-evolving. Technology is creating new opportunities for different types of command and control, and new types of command and control are creating new aspirations for technology. The question is how to manage this process, how to achieve a jointly optimised blend of socio and technical and create the kind of agility and self-synchronisation that modern forms of command and control promise. The answer put forward in this book is to re-visit sociotechnical systems theory. In doing so, the problems of 21st century command and control can be approached from an alternative, multi-disciplinary and above all human-centred perspective. Human factors (HF) is also co-evolving. The traditional conception of the field is to serve as a conduit for knowledge between engineering and psychology yet 21st century command and control presents an altogether different challenge. Viewing military command and control through the lens of sociotechnical theory forces us to confront difficult questions about the non-linear nature of people and technology: technology is changing, from platform centric to network centric; the interaction with that technology is changing, from prescribed to exploratory; and complexity is increasing, from behaviour that is linear to that which is emergent. The various chapters look at this transition and draw out ways in which sociotechnical systems theory can help to understand it. The sociotechnical perspective reveals itself as part of a conceptual toolkit through which military command and control can be transitioned, from notions of bureaucratic, hierarchical ways of operating to the devolved, agile, self-synchronising behaviour promised by modern forms of command and control like Network Enabled Capability (NEC). Sociotechnical system theory brings with it a sixty year legacy of practical application and this real-world grounding in business process re-engineering underlies the entire book. An attempt has been made to bring a set of sometimes abstract (but no less useful) principles down to the level of easy examples, design principles, evaluation criteria and actionable models. All of these are based on an extensive review of the current state of the art, new sociotechnical/NEC studies conducted by the authors, and insights derived from field studies of real-life command and control. Time and again, what emerges is a realisation that the most agile, self-synchronising component of all in command and control settings is the human.

This book presents a human factors and ergonomics evaluation of a digital Mission Planning and Battle-space Management (MP/BM) system. An emphasis was placed on the activities at the Brigade (Bde) and the Battle Group (BG) headquarters (HQ) levels. The analysts distributed their time evenly between these two locations. The human factors team from Brunel University, as part of the HFI DTC, undertook a multi-faceted approach to the investigation, including: - observation of people using the traditional analogue MP/BM processes in the course of their work - cognitive work analysis of the digital MP/BM system - analysis of the tasks and goal structure required by the digital MP/BM - assessment against a usability questionnaire - analysis of the distributed situation awareness - an environmental survey. The book concludes with a summary of the research project's findings and offers many valuable insights. For example, the recommendations for short-term improvements in the current generation of digital MP/BM system address general design improvements, user-interface design improvements, hardware improvements, infrastructure improvements and support improvements. In looking forward to the next generation digital MP/BM systems, general human factors design principles are presented and human factors issues in digitising mission planning are considered.

The integration of Human Factors in Land Use Planning and Urban Design (LUP & UD) is an exciting and emerging interdisciplinary field. This book offers practical guidance on a range of Human Factors methods that can be used to rigorously and reliably explore LUP & UD.It provides new ways to interpret urban space and detail context sensitive analysis for the interpretation and design of our surroundings. The methodologies outlined allow for the consideration of the technical aspects of the built environment with the necessary experience and human centered approaches to our urban and regional settings. This book describes 30 Human Factors methods for use in the LUP & UD context. While it explores theory, it also focuses on the question of what Human Factors methods are; their advantages and disadvantages; step-by-step guidance on how to carry them out; and case studies to guide the reader. Describes the practice and processes associated with urban and regional strategic planning Constructed so that students, practitioners, and researchers with an interest in one particular area of Human Factors can read the chapters independently from one another

Illustrates a contemporary review of the status of Distributed Cognition (DCOG) Presents examples of the application of Event Analysis of Systemic Teamwork (EAST) method Presents examples of the application of Event Analysis of Systemic Teamwork (EAST) method Discusses the metrics for the examination of social, task, and information networks Provides comparison of alternative networks with implications for design of DCOG in systems

During the course of any sporting event, critical cognitive and physical tasks are performed within a dynamic, complex, collaborative system comprising multiple humans and artifacts, under pressurized, complex, and rapidly changing conditions. Highly skilled, well-trained individuals walk a fine line between task success and failure, with only slightly inadequate task execution leading to the latter. Promoting cross-disciplinary interaction between the human factors and sports science disciplines, Human Factors Methods and Sports Science: A Practical Guide provides practical guidance on a range of methods for describing, representing, and evaluating human, team, and system performance in sports domains.Traditionally, the application of human factors and ergonomics methods in sports has focused on the biomechanical, physiological, environmental, and equipment-related aspects of sports performance. However, various human factors methods, applied historically in the complex safety critical domains, are suited to describing and understanding sports performance. This book delineates the similarities in the concepts requiring investigation within sports and the more typical human factors domains. The book’s focus on cognitive and social human factors methods rather than mainly on the application of physiological ergonomics approaches sets it apart from other books in either field. It covers eight categories of human factor methods: data collection, task analysis, cognitive task analysis, human error identification, situation awareness measurement, workload measurement, team performance assessment, and interface evaluation methods. Constructed so that each chapter can be read non-linearly and independently from one another, the book provides an introduction and overview to each Human Factors topic area, and of each method discussed, along with practical guidance on how to apply them. It also includes detailed descriptions of the different methods, example applications, and theoretical rationale. This allows the concepts to be easily found and digested, and the appropriate method to be easily selected and applied.

Human Factors in Automotive Engineering and Technology imparts the authors' scientific background in human factors by way of actionable design guidance, combined with a set of case studies highly relevant to current technological challenges in vehicle design. The book presents a novel and accessible insight into a body of knowledge that will enable students, professionals and engineers to add significant value to their work.

Over the past decade, Cognitive Work Analysis (CWA) has been one of the popular human factors approaches for complex systems evaluation and design applications. This is reflected by a diverse range of applications across safety critical domains. The book brings together a series of CWA applications and discussions from world-leading human factors researchers and practitioners. It begins with an overview of the CWA framework, including its theoretical underpinnings, the methodological approaches involved (including practical guidance on each phase), and previous applications of the framework. The core of the book is a series of CWA applications, undertaken in a wide range of safety critical domains for a range of purposes. These serve to demonstrate the contribution that CWA can make to real-world projects and provide readers with inspiration for how such analyses can be practically carried out. Following this, a series of applications in which new approaches or adaptations have been added to the framework are presented. These show how practical applications feedback into the theories/approaches underpinning CWA. The closing chapter then speculates on future applications of the framework and on a series of new research directions required in order to enhance its utility. In emphasising the practical realities of performing CWA, and the real-world impacts it can provide, the book tackles several common misconceptions in a constructive and persuasive way. It provides a welcome demonstration of how CWA can be a powerful ally in tackling complexity-related problems that afflict systems in all areas.

This book provides an overview of, and practical guidance on, the range of human factors (HF) methods that can be used for the purposes of accident analysis and investigation in complex sociotechnical systems. Human Factors Methods and Accident Analysis begins with an overview of different accident causation models and an introduction to the concepts of accident analysis and investigation. It then presents a discussion focussing on the importance of, and difficulties associated with, collecting appropriate data for accident analysis purposes. Following this, a range of HF-based accident analysis methods are described, as well as step-by-step guidance on how to apply them. To demonstrate how the different methods are applied, and what the outputs are, the book presents a series of case study applications across a range of safety critical domains. It concludes with a chapter focussing on the data challenges faced when collecting, coding and analysing accident data, along with future directions in the area. Human Factors Methods and Accident Analysis is the first book to offer a practical guide for investigators, practitioners and researchers wishing to apply accident analysis methods. It is also unique in presenting a series of novel applications of accident analysis methods, including HF methods not previously used for these purposes (e.g. EAST, critical path analysis), as well as applications of methods in new domains.

How can we design transport environments that cater to the situation awareness needs of different end-users? This book answers this question by showcasing how state-of-the-art human factors theory and methods can be used to understand how situation awareness differs across drivers, cyclists, motorcyclists, and pedestrians and creates new designs that cater to these diverse situation awareness needs. Written by experts in the field and based on a major program of work funded by the Australian Research Council, this book outlines the distributed situation awareness model and provides practical guidance on how to study situation awareness naturalistically and how to create designs that support, rather than hinder, situation awareness. The book closes by outlining outline a generic framework to support similar applications in other areas, and discusses future applications in areas such as vehicle automation, artificial intelligence, and cybersecurity.Features Challenges traditional road safety analysis, design processes and conventions Outlines a novel on-road study methodology for analyzing naturalistic interactions among drivers, cyclists, motorcyclists and pedestrians Presents a review of state-of-the-art situation awareness theory and methods Provides practical guidance on a series of human factors methods Describes a framework to support the design of transport environments Evaluates new intersection concepts that encompass features designed to prevent collisions at intersections
