Discovering the basis for expertise is a task fraught with difficulties, but Crandall, Klein, and Hoffman provide the practical guidance of experienced CTA practitioners. They uncover their mental models, critical cues, and strategies for organizing knowledge and adapting routines. This book collects the resources one needs to become expert at using new tools to support cognitive work.(David Woods, Institute for Ergonomics, Ohio State University)
This is probably the best guide I have read to capturing the essence of tacit knowledge in decision making. An excellent synthesis of the academic and the practical, and a major contribution to the field.(Dave Snowden, Founder, Cognitive Edge)
What a gem! Finally, those who are interested in understanding how people in organizations acquire, retain, maintain, interpret, represent, and use knowledge in their jobs have a practical set of tools to follow and apply. A refreshing, welcome, and much-needed resource book. Bravo!(Eduardo Salas, Department of Psychology and Institute for Simulation & Training, University of Central Florida)
Cognitive task analysis (CTA) is an immensely important approach to evaluating the development, implementation, and use of complex systems. Working Minds is a one-of-a-kind handbook in which highly qualified authors not only provide practical guidance for conducting CTA but also address fundamental cognitive issues that support the techniques. It will prove an extremely valuable resource for practitioners, scientists, systems engineers, and students interested in cognitive systems and workplace evaluation.(Vimla L. Patel, Director, Laboratory of Decision Making and Cognition, Columbia University)

This book gives a number of case studies of all phases of CTA projects. Even before interviews begin, there is a Preparation phase, wherein the CTA practitioners learn enough about the job, profession, and field of work so that they can ask intelligent questions and recognize relevant answers. Then Knowledge Elicitation follows, through interviews, questionnaires, brain-storming sessions, etc., usually involving two analysts, one to lead the enquiry, the other to record the results.
In the Analysis phase the results are collated, correlated, and represented in some graphical or tabular form so that the pattern of cognitive capabilities and their inter-relations can be depicted and understood. The patterns that may emerge include Hierarchical Task Analysis (the task logic of entailment and subsumption), and Procedural Task Analysis (the linear and concurrent sequence of activities), and these may be represented with Skills Lists, Mind Maps, Dimensional Distributions, etc.
The motivation to engage in this type of analysis is often the need to train new recruits more proficiently or replace retirees more efficaciously. So Cognitive Training is a very important part of the exercise, and the findings must be interpreted in such a way as to facilitate this process. Instructional Analysis is therefore based on the previous findings, and both the content and the process of training are improved as a result. In the Knowledge Society this is by far the most sensible approach to training. How many of the Knowledge Working Skills are analyzed, formalized, and instructed in this way? Not nearly enough so far - not even in Learning Facilities or Knowledge Factories - but it is a waste of time, money, and effort to train in any other way, so we can hope that CTA is the wave of the future!
The book makes cognitive systems engineering and its methods much more accessible and comprehensible than any resource I've previously encountered. The book makes the methods described accessible to the novice who has never used them, while also providing details of interest to people who have experience using the methods. For example, it includes a very practical, descriptive, and well-organized walk-through of the cognitive task analysis process that extends from preparation all the way through to its contributions to system design and evaluation.
The book also includes a primer on cognition geared toward the systems developer and which is arguably an important foundation for anyone involved in developing technology that interacts with people performing cognitive work (e.g., information processing, decision making, anomaly detection, troubleshooting,...). The book addresses cost factors associated with cognitive task analysis and other cognitive systems engineering methods (and describes what cognitive systems engineering is and is not - thank you!) throughout, and is full of examples used to demonstrate how cognitive systems engineering methods have been successfully used in the past.
Every systems, human factors, and software engineering student and practitioner needs to read this book!!
Working Minds brings the `intuitive' aspect of decision into focus with the `rational' aspect. This is one, very large contribution. A small disappointment was the absence of teleonomics and its relationship with cognitive task analysis. Also, perhaps a sequel will say more about principles and rules for selecting human vs. automatons during a system design activity.
As computers in general and process formalization in particular encroach further into our lives and as litigation looms larger over those who cannot show that they exercised due process in their work, cognitive task analysis becomes basic, foundational, in business, government and academia. Working Minds helps discover how to lay such foundation.
Highly recommended for anyone in the field - I only wish it had come out sooner.
