Web Usability Study
due in two weeks
Conduct a usability analysis of the Leo Burnett website at
http://www.leoburnett
.ca.
(Note that this has a .ca ending; the .com website does not have the information
that you are being asked to find.)
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 you work as a staff support person at a university.
A marketing professor wants to use some information and video clips
from this website in his classes and needs you to confirm that you can
find these things when s/he gets permission to use them.
Your task is to find this information on the company website as
quickly as possible.
"Your task is to find five 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 your name or 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."
- At the start of each session, open a new browser screen to the URL above.
- 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 serious 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 as quickly as possible,
directly reading to the participant anything that is in quotes:
- "The professor needs to get permission to use materials from this
website in his classes.
- Who is the company CEO?
- In what city is she or he located?
- What is his or her telephone number?
- Print the page showing this information."
- "This website is supposed to have a video of an advertising campaign
for Visa free groceries for a year giveaway.
The professor wants to download it to show his classes.
Find that particular video and print the page that shows it as evidence
that you know where to go to get it."
- "The professor has two students who have asked about working for
this company.
- Who is the Global Head of HR in the Chicago office?
- What is his or her telephone number?
- Print the page showing this information."
- "Assaulted Women's Helpline has a video about verbal abuse.
Find that particular video and print the page that shows it as evidence
that you know where to go to get it."
- Repeat the Task A 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.
