Navigation Design vs Structure
 structure (undeniably IA) is the map of how things
are related
 navigation design (definitely UX, but not so cleanly
IA) involves the actual display that conveys the
underlying structure to users

8. Navigation
choosing things like
 location
 color conventions
 format (drop menus, flyouts)
 orientation cues

Good + Bad = Bad
 structure and navigation design are
INTERDEPENDANT
2/20/2013
 bad structure can’t be fixed by good interface
 bad interface will obscure and negate good
structure

Orienting and Navigating
it’s hard to know if you’re ‘there’ if you don’t know
where you are
Orienting: Where am I?
Content Interaction: What is this? Is this what I want?
Navigating: Where else can I go?

Orientation Test
People starts in the middle most of the time, usually
from google or a random link someone posted
somewhere. So do that. Now:
1. What site are you on?
2. What page are you on?
3. What section are you in?
4. What’s nearby?
5. Can you tell exactly where in the site you are?
6. Could you navigate back to this page tomorrow
from the site’s homepage?

Navigation Stress Test by Keith Instone
1. Ignore the home page and jump directly into the
middle of the site.
2. For each random page, can you figure out
where you are in relation to the rest of the site?
What major section are you in? What is the
parent page?
3. Can you tell where the page will lead you next?
Are the links descriptive enough to give you a
clue what each is about? Are the links different
enough to help you choose one over another,
depending on what you want to do?

these vary based on the context

 efficient tab order/behavior
 descriptive alt tags for images
 text labels for buttons
(or at least appropriate alt messaging)
 link size / spacing
(poor vision / big finger compatibility)

conventions may be boring,
but they are super useful
 any time you introduce a NEW paradigm,
you INCREASE the learning curve
2/20/2013
 seconds are valuable in our A.D.D. world,
so you better make it WORTH it, or users will not be
pleased.
 It’s only worth it if the new paradigm is MUCH
BETTER, or sometimes, MUCH COOLER will let you
get by, but that’s risky.

for a significant % of users and tasks
so don’t be a hater, include alternatives like:

sitemaps are a last resort
 don’t abandon your down-trodden
2/20/2013
 if you are working with a CMS, avoid an out-of-date
sitemap through automation
 good for SEO, so there’s that
 valuable check on site structure—if you can’t
create a reasonable site map, you’re probably
doing it wrong
32 SI658 Information Architecture

indexes
2/20/2013
 alphabetical list of
topics
 okay to list things
multiple times under
alt terms
 usually alphabetized
by TOPIC
 may want to use:
• term permutation
• permutation of terms

Marti’s notes on guides
 tend to be video now
 short = less than 2 min
 usually introduce a product/service and what you
can DO on the site
 if your GUIDE needs a TOC, it’s probably a bad sign
 12% of people will ever look at this
 4% of those guys will view the whole thing

 netflix – everything you’ve watched (on netflix), and
maybe how you rated it
 facebook – everything about you

customization
2/20/2013
 everybody’s got it, (almost) nobody’s doing it
 probably LOVE it where you use it
 probably don’t use it 95% of the time when it’s
available
 not usually a UX drawback, but not easy to justify
the ROI
