A Usable Summary of Discount Usability Engineering
What
follows is a five point Discount Usability Engineering approach developed
through study of many other DUE approaches.
It is meant to be simple and concise in order to maintain maximum ease
of use. This summary should include the
reason that usability itself is needed.
This reason is presented in the section “Why is usability important in
E-Commerce?” of The Paper
1. Know
your users.
Discount Usability Engineering always starts with one principle. This is to simply know your user. Begin by asking questions like,
·
Who uses your Web site?
·
Who buys your products?
·
What would they want to
see?
If a developer knows the answers to these questions, and keeps them in
mind, he immediately begins to create sites that are more user-oriented, and
therefore more useable.
2. Watch your users use your
website.
Creators
of tools naturally use those tools with ease.
Unfortunately, the creator is not the user. Watching only five people use your site can reveal many specific
problems that you would have never come up with on your own:
1. Ask a user
to use your website and speak aloud about the choices he/she is making
2. Watch the
user and take notes
3. Apply what
you learn
3. Navigation
The top two reasons users click away
from sites are confusion and the fact that they can’t find what they’re looking
for. You might not have what they want
in the first place, but if you do, then you want them to find it easily. These are simple ways to make your site more
navigable:
·
2-3 clicks to any solution
·
Effective search engines
·
2 things always in view:
·
useful functions (i.e. shopping cart)
·
system status (where am I? - simple urls can help this)
·
Be consistent across the whole
site
·
Don’t use frames
3. Latency
(download time)
Second
only to navigability, slow download time is listed by users as the reason they
click away from a site. To ensure users
can access your pages:
·
All pages should be less than 30 Kilobytes
·
This will ensure even modem users download times of less
than 8-seconds
·
Server Reliability with the ability to handle peak load
times
·
A user should never receive a denial of service
5. Simplicity
Surveys of users consistently reveal
that they would rather have sites that download fast and are easy to navigate
than sites that are loaded with eye candy.
·
Practice minimalist
design
·
Every extra unit of information competes with
relevant units of information and diminishes their relative visibility.
·
Also, to maintain simplicity:
·
Don’t use animation
·
Don’t require extra software (plug-ins) to use your site
And, B2C specific
Points:
These
points are formulated in response to the top problems listed by users regarding
B2C E-Commerce sites.
- Put extra effort into giving product
information.
- Never force disclosure of any user
information before it is necessary.
- Make shipping information clear even
before a user makes a move to purchase.
- Security information
should be clear and concise.
- 1-800 number and physical location
should be available.
