But we can try to help
 Project Ernestine
 NYNEX was going to buy new workstation for their
telephone operators
 Each second saved per call saves $3M/yr.
 Gray and John used CPM-GOMS to model use of
new workstation
 Discovered it would be 3% slower than original
 NYNEX did not buy workstation
 Prevented mistake, saved $2M/yr.

A Note about Drawing Skills
 Good drawing skills are not required…
 Stick figures, scribbles, boxes, lines, and
annotations are perfectly acceptable! Quality is
not important, only idea and quantity.
 However, you can take a drawing class if you want
to get better
 ASUW Experimental College offers classes:
• Drawing for Absolute Beginners

HCDE 518
LECTURE – WHAT IS DESIGN?
University of Washington
HCDE 518
What is Design?
Creative endeavor
 Process of creating or shaping tools or
artifacts for direct human use
Outputs are things
people-centered concerns
Processes, methods
University of Washington
HCDE 518
Characteristics of Design
 Design…







is conscious
keeps human concerns in the center
is a conversation with materials
is creative
is communication
has social implications
is a social activity
University of Washington
HCDE 518
Design vs. Engineering
 Engineering





Make a mostly-known outcome possible
Construct a sturdy bridge based on specifications
Concerned with what can be done
Reliance on well-established formulae
Humans may or may not be directly “in the loop”
 Design




Envision new possibilities, new outcomes
Determine what outcome should result among infinite possibilities
Reliance on process over formulae
Humans are central actors “in the loop”
University of Washington
HCDE 518
Design vs. Art
 Design (as we regard it) concerns the creation
of something useful and usable
 Art does not bother with this restriction
 The test: how to deem what is “good”?
University of Washington
HCDE 518
Other Contrasts
 Interface vs. interaction design
 Artifact versus sequence
 Graphic < interface < interaction < user experience
 Usability vs. user experience (UX) design
 Evaluation versus holistic design
 Designing it right vs. the right design
University of Washington
HCDE 518
design vs. Design
 design: the general activity we’ve been talking
about so far
 Design: the formal field, including theory,
methods, literature, and practice

Can anyone be a designer?
 Don Norman says “yes”
 Mostly in the “design” sense
 Bill Buxton says “no”
 Mostly in the “Design” sense
 What do you think?

What is designed?
 “Look around you. The only
thing not designed is Nature.”
 David Kelley
 Anything consciously intended
for human use is designed
 Often poorly, though :(
University of Washington
HCDE 518
Why is design hard?
 Interface design is multidisciplinary
 Judging/predicting which designs will be
successful and which will not is difficult
 It is simply hard to come up with good
solutions
 The space of “the possible” is vast compared to
the space of “the good”
University of Washington
HCDE 518
Why is design hard?
 All design involves making tradeoffs
 Can’t maximize everything
 Good designs are non-obvious
 Humans are unpredictable
 Humans make errors
 Mistakes
 Slips
 Design relies on process expertise, not knowledge
expertise
University of Washington
HCDE 518
Core skills of design
 To synthesize a solution from all of the relevant
constraints, understanding everything that will make
a difference to the result
 To frame, or reframe, the problem and objective
 To create and envision alternatives.
 To select from those alternatives, knowing intuitively
how to choose the best approach.
 To visualize and prototype the intended solution

Design is not just “lipstick on a pig”
 Not just changing how things look
 Or making things pretty
 Or designing graphics
University of Washington
HCDE 518
Interaction design mantras
 “The user is not like me.” –Don Norman
 “The best way to have good ideas is to have
lots of ideas.” – Linus Pauling
 “Fail often to succeed sooner.” – IDEO
 “Enlightened trial-and-error succeeds over the
careful planning of the lone genius.” – IDEO
University of Washington
HCDE 518
“The user is not like me”
 Why not? (from Norman)
 Designers are much more familiar with the
interface and with the problems being solved than
users.
 Designers are confident. Users are often fearful.
 Designers work in settings that are different than
the context in which the product may be used.
 Designers may have different skills than users
(e.g., perceptual, cognitive, or domain skills).
University of Washington
HCDE 518
Repeat it out loud
 “The user is not like me”
