Human Factors in System Design, Development, and Testing describes engineering system design as a behavioral process, a process which raises questions the designer must answer. It focuses on the concepts underlying the design process, culminating in a behavioral theory of the design process. Special effort has been made to depict human facto

An easy-to-use, in-depth manual, Human Factors Methods for Design supplies the how-tos for approaching and analyzing design problems and provides guidance for their solution. It draws together the basics of human behavior and physiology to provide a context for readers who are new to the field. The author brings in problem analysis, including test and evaluation methods and simple experimentation and recognizes the importance of cost-effectiveness. Finally, he emphasizes the need for good communication to get the new product understood and accepted. The author draws from his corporate experience as a research and development manager and his consulting practice in human factors and design.

Human factors measurement has characteristics that set it apart from psychological or engineering measurement and for that reason, human factors testing and evaluation deserves special treatment. The many excellent texts available in the behavioral area do not give an adequate picture of this topic, and this is particularly unfortunate because testing and evaluation (T&E) is an integral part of human-machine system design and operation. The emphasis in this book is on why and how to conduct such testing. One of its outstanding features is its pragmatism; based on his past experience in system testing, the author recognizes the difficulties that occur in testing and indicates how these may be overcome or minimized. Special attention has been paid to the context in which T&E is conducted. Although the book contains detailed procedures for performing T&E, the logic and the conceptual foundation of testing have not been overlooked. Comparisons are made with laboratory-centered experimentation. For those with research interests, the author points out the many research questions that can be answered by system testing. An illustrative case history of a T&E program for a fictional system has been included to provide ``real life'' context. Special problem areas in T&E are emphasized, in particular human error data collection, the evaluation of computerized systems and software, the measurement of maintenance technician and team performance; workload and training effectiveness testing. Special attention is also paid to environmental testing (e.g. temperature, lighting, noise, vibration, etc.). One chapter reviews all the relevant T&E literature including government documents that may not be readily available to the general reader. As part of the preparation for writing this text a survey was made of 45 distinguished T&E specialists in order to determine their characteristic T&E practices.The book will be useful not only to the human factors professional who specializes in T&E, but to all students and practitioners interested in human factors and work measurement.

In April 1991 BusinessWeek ran a cover story entitled, "I Can't Work This ?#!!@ Thing," about the difficulties many people have with consumer products, such as cell phones and VCRs. More than 15 years later, the situation is much the same-but at a very different level of scale. The disconnect between people and technology has had society-wide consequences in the large-scale system accidents from major human error, such as those at Three Mile Island and in Chernobyl. To prevent both the individually annoying and nationally significant consequences, human capabilities and needs must be considered early and throughout system design and development. One challenge for such consideration has been providing the background and data needed for the seamless integration of humans into the design process from various perspectives: human factors engineering, manpower, personnel, training, safety and health, and, in the military, habitability and survivability. This collection of development activities has come to be called human-system integration (HSI). Human-System Integration in the System Development Process reviews in detail more than 20 categories of HSI methods to provide invaluable guidance and information for system designers and developers.

In the United States, health care devices, technologies, and practices are rapidly moving into the home. The factors driving this migration include the costs of health care, the growing numbers of older adults, the increasing prevalence of chronic conditions and diseases and improved survival rates for people with those conditions and diseases, and a wide range of technological innovations. The health care that results varies considerably in its safety, effectiveness, and efficiency, as well as in its quality and cost. Health Care Comes Home reviews the state of current knowledge and practice about many aspects of health care in residential settings and explores the short- and long-term effects of emerging trends and technologies. By evaluating existing systems, the book identifies design problems and imbalances between technological system demands and the capabilities of users. Health Care Comes Home recommends critical steps to improve health care in the home. The book's recommendations cover the regulation of health care technologies, proper training and preparation for people who provide in-home care, and how existing housing can be modified and new accessible housing can be better designed for residential health care. The book also identifies knowledge gaps in the field and how these can be addressed through research and development initiatives. Health Care Comes Home lays the foundation for the integration of human health factors with the design and implementation of home health care devices, technologies, and practices. The book describes ways in which the Agency for Healthcare Research and Quality (AHRQ), the U.S. Food and Drug Administration (FDA), and federal housing agencies can collaborate to improve the quality of health care at home. It is also a valuable resource for residential health care providers and caregivers.

This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.

Again, while other human factors books ignore the standards, specifications, requirements, and other work products that must be prepared by engineers, this book emphasizes the methods used to generate the human factors inputs for engineering work products, and the points in the development process where these inputs are needed.
