Websites are put to the test every time
someone visits them, but the software used to record the
popularity of a government site does not assess how easy it is to
use.
Sally Whittle explains why.

Guardian, Wednesday February 25, 2004 and The Guardian online
e-Public section.
The chief executive wants to know how the website is doing. So
you ask the IT department to pull up the server records. They show
that hits are growing, page impressions are up, and the search
engine has been getting lots of use. Great, right? Before you pass
those numbers on, think again.
The search engine's popularity could be a sign that users can't
find the information they're looking for. High page impressions
may suggest they're lost, testing link after link. You don't know
because your organisation, like many others in the public sector,
never asked people whether your website is easy to use. "The
website you have is probably a miserable failure," says Jakob
Nielsen, principal of the usability consulting firm, Nielsen
Norman Group. Nielsen has spent the past decade crusading against
complicated menus, badly designed pages and poorly worded home
pages. He says that 80% of public sector websites fail the
usability test, meaning that the average user can't find and use
information quickly and easily.
Usability is a particular issue in the public sector, in which
websites need to be accessed by the whole community: the elderly,
people with low literacy levels and those with visual or other
disabilities. Managers in the public sector have a responsibility
to ensure that everyone in the community can access online
services, says Mark Gardner, website manager at Birmingham city
council. "The site is paid for by its users and we have to be
able to justify their investment. That means usability has to take
priority over design."
When Birmingham redesigned its website two years ago, improving
usability was a top priority. The council worked with a specialist
market researcher to conduct focus groups, asking the community
what it thought of the new site. "We got a lot of feedback,
particularly on the menu and the terminology we used," says
Gardner. "We used that to create a new menu based on eight
categories of content that people can easily understand."
The focus group is an essential component of user-centred
design, which is the holy grail of website usability. "The
idea is to build your website around what users want and how they
think, rather than how your council is structured," explains
Catriona Campbell, managing director of The Usability Company.
"When I visit the council's website, I don't know which
council department I want to contact. I just want to know when the
rubbish is collected on my road."
The first step in improving website usability is to think about
how information is put together on the site - something the
experts call information architecture. "Does one page follow
another in a logical order," asks Campbell. "When I
click on a link, do I have an idea of where I'm going to end
up?" One way organisations can improve information
architecture is to write the headings of web pages (or groups of
pages) onto pieces of paper, and ask users to organise them into
areas they think are related. "This is a really simple and
remarkably effective way to devise a menu structure,"
Campbell says. Where users don't agree on where a page goes,
information can be duplicated or a link created between the two
sections.
Once you have a basic structure in place, Campbell advises
creating a paper prototype of a typical web page, and again
testing the site's design with users. Once this is done, create a
prototype website using basic hypertext mark-up language. It might
seem like a lot of hassle, but Campbell points out that early user
testing often works out cheaper in the long run.
"It's a lot cheaper to move a search button on a paper
prototype than it is to move a button on a fully-functioning
website," she says. Early and frequent testing can offer
warnings on potential problems. When Medway council redesigned its
website last year, the three months spent on user testing helped
reduce overall development time by half, according to website
manager Sean Hale. "It was absolutely worth it because it
opened our eyes to issues that we would never have considered
ourselves, because we know the site and the information inside
out."
The council initially videotaped a series of users trying to
accomplish specific tasks on the existing website, and used the
results to create a priority list for the new site. The usability
team then returned to the users at every stage of development,
while a specific disability working group considered how well the
site worked for people relying on text-to-speech web browsers and
other assisted technology. However, user testing can present
managers with problems. "You'll always get people who say
everything is rubbish.
People contradict themselves all the time and nothing is ever
going to please everyone," says Hale. The best advice is to
take the general point of view, unless an individual points out an
issue that you are obliged to take note of, such as access for
people with specific disabilities. If your website is up and
running, it's still possible to dramatically improve usability
with a few inexpensive and simple changes. For example, traffic
monitoring software can reveal what pages on a website are being
visited, and where visitors leave a site. This can reveal services
that aren't being used or particular stages in a process where
users become confused or lost.
The National Endowment for Science, Technology and the Arts (Nesta)
is responsible for awarding grants to innovative community
projects from National Lottery funds. However, traffic analysis
showed that visitors were often leaving the site without viewing
information on how to apply for grants. "We didn't know we'd
hidden it, but it was apparent people couldn't find the
information," says Maria Stark, Nesta's web manager. Simply
moving this information further up a menu structure, or providing
a link from the home page is often enough to improve usability.
Traffic analysis tools are widely used, but it requires a degree
of skill to interpret these results, says Nielsen. A page might be
unused because it is hidden, but it's also possible that people
don't need that service.
Alternatively, visitors may end up misinformed by content they
have found that is poorly written. In the end, Nielsen says, user
group testing is the only way to really be sure your website
passes the usability test. "There's a tendency to prefer
nice, clinical data to the messy process of sitting down with real
users," he says. "But remember: they don't smell, and
they won't bite. Who knows? They might even be nice about your
website."
