The project group
split into two teams of two to develop alternative designs. As an initial
"seed" of design difference, it was decided that one design would be
threaded and the other linear (see Vocabulary
page for definitions).
During the design
process, an additional major differentiation emerged. The linear design
team chose to focus on one problem implied by several of the scenarios,
especially Ed's: how to present a broad set of interrelated information
in a specific subject area, including a discussion component. The threaded
design team focused primarily on the portion of Cindy's scenario after
she enters the discussion forum (i.e., browsing and posting tasks).
