Metaphor
The following scenario provides a simple metaphor that gives some insight into how a blackboard system works:
A group of specialists are seated in a room with a large blackboard. They work as a team to brainstorm a solution to a problem, using the blackboard as the workplace for cooperatively developing the solution. The session begins when the problem specifications are written onto the blackboard. The specialists all watch the blackboard, looking for an opportunity to apply their expertise to the developing solution. When someone writes something on the blackboard that allows another specialist to apply their expertise, the second specialist records their contribution on the blackboard, hopefully enabling other specialists to then apply their expertise. This process of adding contributions to the blackboard continues until the problem has been solved.

Famous quotes containing the word metaphor:
“Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.”
—Johan Huizinga (1872–1945)
“By metaphor you paint
A thing. Thus, the pineapple was a leather fruit,
A fruit for pewter, thorned and palmed and blue,
To be served by men of ice.”
—Wallace Stevens (1879–1955)
“—fur-petalled chrysanthemum,
squirrel-killer—
is a metaphor only if I
force him to be one....”
—Denise Levertov (b. 1923)
