Usability Testing
No-one would launch a new product onto the
market without testing it, yet every day, websites are published
that have broken links, obstacles and barriers to the user,
confusing architecture and more.
Usability
testing is concerned with the experience that your users have.
In general it aims to predict likely problems your users will
encounter on your website. Testing with users achieves this by
actually observing normal people (or those in your target group)
using your website.
We offer website testing on two levels
Expert heuristic evaluation
A usability specialist tests,
reviews and evaluates the website focusing on the user
experience. Cognitive walk-throughs, identification of barriers
to the user completing tasks, architecture, user interface,
navigation and orientation. Readability of the text content and
more.
Qualitative User Testing
By carrying out user testing, it
conclusively identifies the problems that users do have when
using your website. No speculation, no arguments or debates
between the development team and marketing department, or
between the client and the web developer. Conclusive evidence.
User testing involves recruiting
people (users) who will use your website under observation.
They are in as realistic a situation as possible (as this
improves the results) and are asked to carry out tasks that are
specifically developed to be relevant to the website being
tested.
The users are facilitated through
the process and observed by a usability expert.
The results are collated and
analysed and feedback is provided. The emphasis is firmly on
the qualitative as this has been proven to produce the most cost
effective results for small-scale testing.
As this type of testing is looking
for insights and barriers that contribute to the next stage of
development, then it has been demonstrated that testing with 5
users is sufficient, and it is preferable to carry out multiple
tests, rather than with more users. This means that
qualitative user testing, sufficient for most projects is quick
and inexpensive to carry out.
Quantitative User Testing
Metrics and Quantitative recording
or users activity can also be carried out. However, it is
important to note that the only point of producing metrics or
measurements of any kind is to make a comparison with another
set of metrics: between an existing site and a redesign, between
different options or between your site and your competitors.
In order to ensure data accuracy a minimum of 20 users must be
tested, and preferably a higher number.
Note that usability
testing is NOT carrying out focus groups. In a focus group
situation - where people are asked their opinion of things and
their likes and dislikes, there is a common tendency for the
participants to respond in a way that they think is socially
acceptable in the situation, or to agree or disagree with
someone else present. That is not to say that focus groups are
no good, but they are not particularly useful when it comes to
testing a website. In short, when it comes to using the
internet, what people say they will do and what they
actually do in a real or simulated situation are often very
different.
