Usability Testing and Results
1.1 Purpose
Our usability
goal for groceriestogo.com is to make it convenient and enjoyable for people to
do their grocery shopping online. We have designed our interface to be clean and
intuitive for the user to navigate with the least amount of difficulties.
To ensure that we have accomplished our goal, we have decided to conduct
usability test. The major goal of this test is to identify the usability issue within
the groceriestogo.com site.
2. Problem Statement and Test Objectives
Based on the purpose
of the Usability test, we have thoroughly investigated the Web site of groceriestogo.com
for potential problems and have had users and potential customers do the same. As
the result of this preliminary investigation, we decided that our usability test
will focus on the following scenario:
·
The shopping cart: Will the user be able to add products
to their shopping cart and view the total price? How do they find the process?
·
Login & User registration: Is the registration
process simple and intuitive?
Specifically,
we will examine the degree to which the site meets the following user needs:
·
Intuitiveness of the purchasing procedure and of
identifying crucial information related to grocers and grocery.
·
Easy navigation (intuitiveness of the navigation
elements, naming conventions, arrangement, and other navigation cues)
·
Easy registration: How easy and intuitive the registration
process is.
3. User Profile
While the resulting design of groceriestogo.com should ultimately satisfy all of
the personas, we believe that the first step should be to satisfy the needs of just
one: the primary persona.
The primary personae user for groceriestogo.com was developed by conducting the
persona mapping activity as well as in person conversations with the target demographic.
