Using Visual Tools to Supplement our Left-Brain
(Verbal) Tools
  • Arguing about pictures doesnt seem to acquire
    the same violence as arguing about words.
  • To be useful, a map must contain information
    enough to make it worth our while to study it,
    but not so much that our capacity for
    understanding is overwhelmed.

Mapping Tools
  • Sketching
  • Typical in developing physical products.
  • Not taught to info system developers, whose work
    often suffers from overly precise notations used
    too early.
  • Wiggling a sketching technique using wiggly
    lines to indicate incomplete precision in part of
    the diagram.

Braindrawing a Visual Variant of Brainstorming
  • Participants start a drawing and then pass it on
    others for refinement.
  • After a few cycles, drawings are mounted in an
    art gallery and presented by someone who didnt
    contribute to it.

Right-Braining
  • Goal is to encourage partial thoughts and ideas
    to be conveyed as images (as with the Chapter 10
    lecture notes.)
  • The visual form may reveal ambiguities that the
    verbal form concealed.
  • Every process we use can be right-brained,
    revealing verbal assumptions, stimulating new
    ideas, and letting our left brain relax for a
    change.

    for the following problem
