Develop the Usability Test Documents
There are four basic documents used for hands-on task based usability
testing. These documents are:
-
Waiver
-
Entrance Questions
-
Task Based Questions (the heart of the hands-on
usability test)
-
Exit Questions
If you don't have MS Word you can download a free viewer for Microsoft Word.
Let's look at the purpose of these docments and see a sample of each.
- Waiver - Each test subject should sign a waiver or
consent form, indicating that they are giving permission for you to
take notes (or video/audio tape) them during the testing. Sample
Waiver.
- Entrance Questions - these documents help you collect
demographic information that you can later use when analyzing your results.
Questions include name, age, gender, internet experience and target
audience group. Sample Entrance Questions.
- Task Based Questions - The heart of hands-on usability
testing is the Task Based Questionnaire. During the test, the subject
is sitting in front of a computer with the appropriate starting page
on the browser. The facilitator verbally leads the test subject through
a series of questions/tasks, encouraging them to think out loud. The
facilitator does NOT lead the subject to the answer. Sample
Task Based Questions.
- Exit Questions - At the end of the testing session,
you will want to allow at least 10 minutes for your test subject(s)
to give you their opinion of the site. How easy was it to navigate the
site? What did you like or dislike? What was confusing? Sample
Exit Questions.
Feel free to use the samples above as your template, making changes as
needed to adjust to your specific testing needs. The document that will
require the most work will be your Task Based Questions. Here are some
pointers on how to write your task based questions:
Key Pieces of Info - Think about your site. What key
pieces of information will people need to find on your site? Consider
writing a task/question for each of your key pieces of information.
Top Ten - Have too many key pieces of information, then
test for the "Top Ten" things people need to get from your web
site.
Audience Versions - Don't hesitate to write a slightly
different version of your Task Based Questions for each of your target
audiences. Different target audiences have different needs on your site.
When I create different versions, I usally have a core group of questions
that work for all my audiences (perhaps 60-70% of the questions) with
a few more audience specific questions.
Non-leading Questions - When writing the text of the
question, make sure you are NOT leading your test subject to the answer.
Use common vocabularly and specifically avoid the vocabulary that you
are using in your hot links and buttons. For example, if I wanted to test
the ease of finding the "Campus and Parking Maps" and the link
text was "Campus and Parking Maps", I might word the question
like this, "You are planning on taking your friend to the Texas Memorial
Museum this weekend and you need to find out where you can park."
Simple - the task/question should be simple, so the
test subject can keep it in their mind without reading it. Try to write
the task in the vocabulary of the target audience.
Realistic Scenarios - The Task/Questions should be realistic
scenarios that your target audience would really experience. The point
of the test is to simulte being "the fly on the wall" while
a real person is using your site.
