People-focused knowledge management

Tacit Knowledge: Knowledge that a person possesses unconsciously.
Tacit knowledge may be inaccessible to conscious recall and 
reasoning because it (1) is not well understood; or (2) is highly 
routinized and automatic and has transgressed the recall barrier.
Talk-Aloud: Narrative produced by a person while performing an
activity to reflect aspects under consideration at the time. It is
related to “Think-Aloud,” which is narrative that reflects

the thoughts and reasoning of a person while undertaking a K-I
activity. “Verbal Protocol” is the talk-aloud narrative produced 
by knowledge workers while undertaking K-I tasks.
Task Environment Analysis (TEA): In-depth investigations of how
knowledge workers perform business tasks and the conditions
under which they work. The focus is on knowledge, its manifes-
tations, presence, use, etc., and how important knowledge is, given
the environment’s driving forces. Its focus is on how the task is
performed, what its inputs and deliverables are, and, to some
extent, how it is used by “customers.” Most TEAs also take the
next step of considering how deliverables may be used as business
and operating practices change, and how the task may be modi-
fied and strengthened by changing its organization or operation or
by introducing different perspectives or different support systems.
Thinking about Thinking: Being consciously able to engage in meta-
reasoning and to understand mental processes such as strategies
and models.
Upstream Function: A function that supplies the target function with
work products.
User Interface: The facility of a knowledge-based system that sup-
ports bidirectional communication between the system and its user.
Most user interfaces use natural language-processing techniques
and bit-mapped graphics.
Work Role: The often complex role that a knowledge worker is given
or assumes. The role reflects the passive-active and learner-teacher
behavior. Examples are: expert and team leader; apprentice and
project assistance; and quality controller.
