Usability is like world peace.
We all want it.
But how do we get there?

What is User-centered design (UCD)
is an approach to design
user- that grounds the process
in information about
centered the people who will use
design? the product.
UCD focuses on users through
the planning, design and
development of a product.

User-centered design
goes a little something like this…
Phase 1
Analysis
Phase 2
Design
Phase 3
Evaluation
Phase 4
Deployment

User-centered design

User-centered design
is common sense.
Phase 1: Analysis
How would you like your hair cut?
Phase 2: Design
Snip, snip.
Phase 3: Evaluation
Here’s a mirror. What do you think?
Phase 4: Deployment
Have a great day!

Phase 1: Analysis
Understand
the people
who will use
the design.

Listen to people who might use
your design. Use any means necessary.
Hint:
They’re probably not the
people who are paying you.

Create personas to embody
groups of users who are similar.
Ethel LeDuc
82 years old
Ethel spent her adult life as a stay-
at-home mother and wife. Now, she
is proud of being a “grr-grandma.”
Having come of age during the
Great Depression, Ethel is
resourceful and spunky. She doesn’t
shy away from any challenges, and

Primary use of cell phone: study as she once was.
Calling a select set of contacts
(friends and family)

Every decision should directly benefit

Can it make
phone calls?

Can Ethel make a

How many targets can you hit?
Hint:
It’s probably about three.

Phase 2: Design
Solve their
problems.

Look at the big picture first.
People see the forest before the trees.

Sketch a lot of different ideas, fast.
Then throw most of them away.
Hint:
It’s easier to get attached to
ideas that end in .PSD.

Close Photoshop.

Soapbox: Banish lipsum!
Content is design; design is content.

Soapbox: Banish lipsum!
Content is design; design is content.
Designing for a template-
based system?
Anticipate the types of
content and design for them.

Don’t forget Ethel.

A couple of ideas seem to work?
Clean them up and test them.
Hint:
You don’t yet know
if you have a gem or a turd.
Don’t polish too much.

Phase 3: Evaluation
Make sure
the design
works.
Early.
And often.

Know your limitations.
You won’t catch everything.

Be a voyeur. Use any means necessary.

Phase 4: Deployment
When you’ve
gotten it
right…
Launch.

Getting started
How can
you tip-toe
into user-
centered
design?

If you want to win the race,
you have to run the entire course.

Each phase builds on the previous.
Phase 1
Analysis
Phase 2
Design
Phase 3
Evaluation
Phase 4
Deployment

Design without analysis
won’t solve the right problems.
You need to know
why they want to
fire a gun.

Evaluation without design
will find obvious flaws.
Testing what’s
obviously wrong
is a waste of
effort.

Deployment without evaluation
will disappoint your customers.
It’s not nice to
make Ethel cry.
Not good
business, either.

So start at the very beginning.
Listen to people.
Empathize. The rest will follow.

Thank you!
