Web Usability Study
due in two weeks
Conduct a usability analysis of Fry Steel at
http://www.frysteel.com.
Inform participants that they are to find all requested information as quickly
as possible.
- Conduct the usability study on four people, including a convenience sample
of yourself and three other convenient participants:
- Conduct the first session on yourself without first looking
through the website.
That is, the session that you run on yourself should be the very first
time that you look at the web site.
- Start each session by briefing the participant:
"I will be asking you to look at the website of a real company.
Let's pretend that your boss needs some information about this company
and its products, and your task is to find this information on the
company website as quickly as possible.
"I will be asking you to find six pieces of information on the
website.
While you are doing this, I will be taking notes regarding how you
found each piece of information and how long it took you to complete
each task.
"I am not recording any identifying information about you on these
notes.
They will be submitted to my professor with my project report as
evidence that I conducted this session, but they will be returned back
to me when my report is returned.
The professor is not keeping any data and is merely interested in
seeing evidence that I have conducted this usability study.
We should be done within about ten minutes.
"If you would want to quit at any time, just let me know and you may
take my notes with you."
- DO NOT start each session with a web browser open to the splash
page at the link above and do not start the session on any other
page.
Open only the browser and ask the participant type the test site
URL into the browser and to answer the first question as quickly as
possible.
- At the end of each session, debrief the participant with regard to
confidentiality, anonymity, and how you will be reporting the data.
- In conducting the usability study, use the following as your topic guide
(to include issues above).
- Do not allow the participant to use any website or external search
functions except as a last resort - use of a search function is proof
that the website has a usability problem.
- Create a paper form to use in recording your observations of each
participant:
- Observe and record the steps (e.g., menu items used) that each
participant takes to complete each task.
- Record the approximate amount of time that was taken to complete
each task.
- Record any affective comments that the participant makes.
- Ask the participant to complete each of the following:
- Find this company by typing the FrySteel.com URL into the browser
and then complete the following tasks as quickly as possible.
- Is this company ISO9001 certified?
Print the page that shows this answer.
- What is the list of products that this company makes?
Print the page that lists these products.
- What sizes of Kovar does this company supply?
Print the page that lists these sizes.
- How would this company ship products to Texarkana customers?
Print the page that shows this answer.
- How would you contact this company by email?
Print the page that shows this answer.
- Repeat the Task B above.
- In addition to tracking the steps and the time to complete each
task, note that you must also report measures of likability in your
report (below).
This necessarily requires that you take likability measures during
the session.
- Your written report must contain the following elements:
- research objectives
- methodology
- findings:
- utility (does the site do what it is apparently supposed to do?)
- usability (can the user easily figure out how to use the site?)
- ease of learning (how easily can the user learn to move
around the site?)
- efficiency of use (e.g., how much time to complete tasks?)
- memorability (can the user repeat a task?)
- error frequency and severity (how often and how serious
are navigation errors?)
- likability (user satisfaction)
- conclusions
- recommendations
- In a separate folder, include the forms with your handwritten notes of your
observations of each study participant stapled to the pages that each
participant printed.
These notes would include comments on the menu items that were selected in
attempting to complete the task, the amount of time (in seconds) that the
participant required to get through various parts of the task, causes of these
times (download times, errors working through links, etc.), the types of
errors that a person made while trying to find information, the number of
attempts that were made before success or abandonment of the assigned task,
comments made by the participant regarding usability, likability,
frustration, and etc.
Do NOT put the participant's name on your observation notes.
- This is an individual assignment that requires you to make your own
observations and to write your own report.
