Bailey, INL ART TDO Quality Assurance Date ABSTRACT This report describes a methodology to conduct a work domain analysis in preparation for the development of operational concepts for new plants. This method has been adapted from the classical method described in the literature in order to better deal with the uncertainty and incomplete information typical of first-of-a-kind designs. This report outlines the strategy for undertaking a work domain wnalysis of a new nuclear power plant and the methods to be used in the development of the various phases of the analysis. Basic principles are described to the extent necessary to explain why and how the classical method was adapted to make it suitable as a tool for the preparation of operational concepts for a new nuclear power plant. Practical examples of the systematic application of the method and the various presentation formats in the operational analysis of advanced reactors are provided. NOTE: For additional information, readers are referred to previous reports listed in the Reference section of this report. vii viii CONTENTS ABSTRACT ................................................................................................................................................ vii ACRONYMS ............................................................................................................................................. xiii 1.

    UNCLASSIFIED Cognitive Work Analysis: Foundations, Extensions, and Challenges Neelam Naikar Air Operations Division Defence Science and Technology Organisation DSTO-GD-0680 ABSTRACT This essay, which reviews the foundations, extensions, and challenges of cognitive work analysis, is based on a keynote address delivered at the 10th International Naturalistic Decision Making Conference held in Orlando, Florida from 31 May to 3 June, 2011. It describes the origins of cognitive work analysis and the utility of this framework for designing ecological interfaces, as well as for tackling a variety of other design challenges, particularly, the design of teams or organisations. Also featured in this essay is the formulation of a methodological perspective of cognitive work analysis, which complements the conceptual accounts provided by Rasmussen (1986), Rasmussen, Pejtersen, and Goodstein (1994), and Vicente (1999). Finally, this essay highlights the latest shift in research emphasis from work domain analysis, the first dimension of cognitive work analysis, to the subsequent dimensions of this framework.

To help them perform their jobs effectively, it is indisputable that first we need to understand the nature of their work. Only then is it possible to design interfaces, teams, or training systems, for instance, that will enable workers to meet their work demands successfully – in a way that is safe, productive, and healthy (Vicente, 1999).

Toward An Understanding Of Field Studies Abstract Field studies have frequently been advocated as a means for understanding cognitive activities in naturalistic settings. However, there are several fundamental obstacles that one has to overcome to conduct a field study. This paper discusses two of these obstacles in the context of studying problem solving in complex environments: defining goals of a field study and justifying methods used in data analysis. Based on our experience from a recently finished field study, we outline a framework for understanding the nature of field studies and suggest a specific approach to data analysis. We argue that the goal of field studies should not be limited ot hypothesis testing, and that the process of data analysis in field studies can be viewed as an inductive abstraction process.

While in the past its progress relied on expertise coming mostly from medicine, today it receives contributions from many different areas of research such as electronics, chemistry, biology, physics, mathematics, mechanical engineering, materials engineering, and informatics. Such fast development has produced an immense variety of well-accepted equipment and medical procedures for diagnosis and therapy. However, it also requires the development, transference and adaptation of safety programs, formerly developed in other industries, to be implemented in medical procedures as well as equipment operation, equipment design and production, hospital interoperability, medical records, cloud storage, and so on. Clinical engineers, used to dealing mostly with medical equipment management techniques, found themselves overwhelmed by safety demands associated with the use of such technologies. Worse, few academics worldwide are familiar with safety programs applied to the healthcare area. As one of the participants in the implementation

Systems Design Engineering, University of Waterloo • PEng. Professional Engineers of Ontario Current status: Professor, Systems Design Engineering, University of Waterloo; Director, Centre for Bioengineering and Biotechnology, University of Waterloo Homepage: aidl.uwaterloo.ca Biography: As a systems design engineering student, we experienced a very broad ranging technical and design oriented program where one pillar of the program was ergonomics. I quickly gravitated to this elective direction, eventually completing a minor in psychology along with my engineering degree. While interviewing for graduate schools, I met Kim Vicente, a dynamic young professor who was just starting at the University of Toronto. His ideas and passion for cognitive work analysis and ecological interface design were inspiring and allowed me to combine my interests in both psychology and engineered systems. After my master's degree at the University of Toronto I worked at Westinghouse in Pittsburgh for a year. At Westinghouse I met a very strong and experienced team of control room and display designers and began to appreciate the challenges and the historical commitment of those who worked in nuclear human factors. It was a domain that had had some serious accidents in the past, had a tight regulatory environment, challenging complexity for the operator, and yet the people who worked in the field were still challenging the boundaries of design, and passionate about finding smart and effective new ways to help humans work. This environment encouraged me to return for a PhD degree at Toronto where I investigated ecological integration concepts in nuclear power displays.

His work has influenced researchers and practitioners in a number of fields including psychology, engineering, sociology and human factors . In more recent years, a large amount of research has been inspired by theoretical and practical aspects of Rasmussen’s work including his models of the boundaries of safe operation and performance and methods such as Cognitive Work Analysis and graphical support for accident investigation such as AcciMaps. E.g., his work on the Risk Management Framework has been cited over 1000 times since its original publication in 1997.
