Cognitive Work Analysis: Toward Safe, Productive, and by Kim J. Vicente

By Kim J. Vicente

This ebook describes, for the 1st time in pedagogical shape, an method of computer-based paintings in complicated sociotechnical structures built over the past 30 years by means of Jens Rasmussen and his colleagues at Risø nationwide Laboratory in Roskilde, Denmark. This procedure is represented by way of a framework known as cognitive paintings analysis. Its target is to aid designers of advanced sociotechnical platforms create computer-based info aid that is helping staff adapt to the unforeseen and altering calls for in their jobs. in brief, cognitive paintings research is set designing for adaptation.

The ebook is split into 4 components. half I presents a motivation by means of introducing 3 issues that tie the e-book together--safety, productiveness, and employee healthiness. The ecological strategy that serves because the conceptual foundation in the back of the publication is additionally defined. additionally, a thesaurus of phrases is supplied. half II situates the information within the e-book in a broader highbrow context by means of reviewing substitute techniques to paintings research. the constraints of normative and descriptive ways are defined, and the reason at the back of the formative process recommended during this publication is explored. half III describes the strategies that contain the cognitive paintings research framework intimately. every one thought is illustrated by means of a case learn, and the results of the framework for layout and examine are illustrated via instance. half IV unifies the subjects of defense, productiveness, and wellbeing and fitness, and exhibits why the necessity for the techniques during this e-book will in simple terms raise sooner or later. additionally, a historic addendum in brief describes the origins of the information defined within the book.

Sample text

Some nuclear power plant operators have to periodically go to a simulator and pass a certification test. The purpose of the test is to make sure that operators have the expertise that is required to operate the plant safely and effectively. The focus during testing is on evaluating whether operators can deal effectively with severe, abnormal events. These fault situations rarely occur on the job, but they can seriously threaten the integrity of the plant and the welfare of the public. During these events, operators are supposed to follow a set of written procedures that tell them what actions to take to cope with different kinds of abnormalities.

It might be that the disagreement results from the fact that we have defined some terms in a way that is different from what you are accustomed to. Thus, you can use the Glossary as a resource to self-check your comprehension of the concepts we introduce throughout the book. Definitions All terms that have been defined are capitalized.

2 Any computer-based system for human work is based on a certain set of assumptions about the work that it is intended to support. Rather than making those assumptions implicitly, the design of information systems should be based on an explicit analysis of work. , Kirwan & Ainsworth, 1992; Meister, 1985; R. B. , Diaper, 1989; Nardi, 1996b; Suchman, 1987, 1995). However, work analysis is not an end in itself but rather a means to derive implications for design. Although we do not discuss design principles per se in this book, we try to show the strong connection between work analysis and design through the use of examples.
