WHAT IS
USABILIT Y?
USABILITY MEANS THAT
SOMEONE SHOULD BE
ABLE TO UNDERSTAND
AND ACCOMPLISH A
TASK INTUITIVELY
WITHOUT THOUGHT
OR FRUSTRATION.


FORM VS
FUNCTION

Sure, both of these tea pots are nice to look
at, but which one is more useable?

Usability is all about the experience,
be it in a tea salon or on the web.


DON’T MAK E
ME THINK.
Steve Krug’s first law of usability states that
a web page should be obvious and self-
explanatory. Be sure the navigation and site
structure are intuitive. Have visual clues and
easily recognizable links so that users can
find what they are looking for.

What do they do?

WHY IS IT SO IMPORTANT?
With billions of websites on the internet
today, your competitors are only a click away.
If you don’t help your users accomplish their
goals, they are bound to head straight to
your competitor.

A usable website creates trust in your
customers and a sense of satisfaction.


YOU HAVE LESS THAN

T WO MINUTES
TO COMMUNICATE
THE FIRST TIME
A PROSPECTIVE
CUSTOMER VISITS
YOUR WEBSITE.

Every page must justify its claim on their
time. If a page doesn’t do that immediately
and clearly, users go elsewhere.

Most don’t even bother scrolling to see
what’s further down the page.


NAVIGATION
Your navigation system should be simple and
clear. Your users should not have to ask the
following questions:

Where am I?

Where should I begin?

Where did they put ______?

What are the most important
things on this page?

Why did they call it that?


WHERE
DOES THIS IMPROVING NAVIGATION
LINK GO? • Users must be able to predict what will
happen if a link is clicked and determine
whether or not it takes them to their goal.
• Information should be organized in a
logical manner.
• The language and organization of the
navigational path must match the user’s
expectations and needs
• The use of ambiguous links can cause
the user to go to the wrong page.
• The use of nonstandard links can cause
confusion.


MORE THAN 83%
OF INTERNET USERS ARE
LIKELY TO LEAVE A WEB
SITE IF THEY FEEL THEY
HAVE TO MAKE
TOO MANY CLICKS
TO FIND WHAT THEY’RE
LOOKING FOR.
-Arthur Andersen, 2001
