Designers make considerably more efficient use of their time
when dealing with a sketchy prototype of their creation,
as it encourages them to focus on high-level design
before expending time on volatile details.
DENIM makes good use of semantic zooming,
allowing designers to choose to work with global structure
or with page-level layout.
Storyboarding is a powerful technique
for rapidly prototyping interaction.
Rather than merely allowing the design of static artifacts
as most rough-prototyping tools do,
DENIM actually allows the specification of some simple behaviour.
WEAKNESSES
DENIM's inability to export a useful work product
isolates it from the rest of the design process;
designers are forced to start over
with a "real" Web site building tool.
Although DENIM provides page-level abstractions when zoomed out,
it doesn't help one abstract site structure concepts
(links remain individual links).
The tool could be improved by adding high-level abstractions
for common Web navigation patterns
(such as ordered sequences, fully connected graphs, and trees).
Sketching is a poor interface for entering text.
DENIM should permit users to type in the names of pages
and the text on pages rather than forcing them to use pen strokes.
