"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

Cognitive task analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. CTA can yield information people need-employers faced with personnel issues, market researchers who want to understand the thought processes of consumers, trainers and others who design instructional systems, health care professionals who want to apply lessons learned from errors and accidents, systems analysts developing user specifications, and many other professionals. CTA can show what makes the workplace work-and what keeps it from working as well as it might.
