"When the designers generated a new
idea in a freehand sketch, they quickly
followed it with several variations. But
those who used a drawing program
tended to focus more on reﬁning the
initial design, without generating design

"Putting ideas to paper is a powerful way
to extend one’s memory."
– Zafer Bilda and Halime Demirkan 2003 **
"... Designers who used paper changed
their goals and intentions more frequently
and engaged in a higher number of
cognitive actions. Changing goals and
intentions while sketching is vital because
it enables you to pivot your initial idea
and to be versatile in your approach."

"Leaving out details can encourage the
team to consider alternative designs."
– Laura Busche
"Consider every time you’ve left
unﬁnished strokes, gray ideas over top
solid shapes, quick side queries, blank
spaces, wobbly lines and ﬁgures. Happens
all the time, right? These indeterminacies,
or “ﬂaws,” which reﬂect our
indecision, are great pointers to new
design directions. We lose these when
we opt for pixel perfection."
– Jim Ross
“Yes, of course, paper prototyping is still
worth doing. It offers you the advantages
of being able to quickly create and test
multiple design directions. However, the
newest digital prototyping tools are
quickly catching up.”
