Experts in a given field possess knowledge and skills
that cannot possibly be captured in anything like a simple
check list. Tapping that knowledge requires a sophisticated
By using methods of Cognitive Task Analysis, Cognitive Work
Analysis and Cognitive Field Research, this research effort
is intended to advance our understanding of the "5-percenters"
in such domains such as weather forecasting and military command
and control. In addition, the research explores the nature
of tasks and modes of reasoning and learning that can impede
the development of expertise and skill and can lead to cognitive
difficulty and error on the part of novices or journeymen,
but also on the part of practitioners who are already considered
to be expert.
This research program involves the creation of methods for
eliciting, preserving, and disseminating the wisdom of experts,
for the benefit of society. The knowledge of the experts also
will underlie new technologies to assist domain experts at
their jobs, technologies that are truly "Human-Centered."
