Executive Summary

The GoBaby! application is designed to provide the most important information needed

to care for a child in an efficient manner. The main design goals revolve around the idea

that the application will be used on a mobile device in a location other than the user s

home (e.g., on the go).

We have created a paper prototype to be used in informal usability testing. Our goal is

to identify potential issues with the application's design. In our test we will ask users to

interact with the prototype to accomplish three main tasks:

1. Create a New GoBaby! Profile

2. Share a Profile With Another GoBaby! User

3. Use GoBaby! To Locate a Nearby Doctors Office or Hospital

This document outlines the details of our usability test plan, to be executed in class on

February 14th. Our methodology, a test script, post-task questions and post-test

questions are included.

Methodology

The GoBaby! iPhone application will undergo usability testing with the following

parameters.

Participants: Five participants will be selected from the Winter Quarter 2010-2011

DePaul University graduate class HCI 440-801. Three women and two men between

the ages of 21-65 will be tested individually. All of the participants are considered to be

comfortable to expert users of computer/mobile technology in general and the iPhone

device in particular.

Testing Environment: Usability testing will take place on:

Monday February 14th 2011

5:45PM-9:00PM

DePaul University Lewis Center

25 East Jackson Blvd. #1217

Chicago, Illinois 60604

The testing room is a standard DePaul University lecture room and will be configured to

facilitate testing. Other usability testing, unrelated to the GoBaby! application, will also

be taking place in the room. Reasonable steps will be taken to create a quiet and

distraction free environment, but there will be no way to create complete privacy for the

participant. The test will not be recorded on video, but may be recorded via audio.

Test Procedure: The usability test will be an informal test using a low fidelity (paper)

test. We have chosen this test method because the application is in an early stage of

development and we do not have the time and resources required for more rigorous

testing. Testing will follow the following format:


2


5/16

1. Introduction: The participant will be greeted by the administering team

member and read a brief introduction. This introduction will provide a

description of the application along with purpose of the test. The test

administrator typically would present the participant with a consent form to

sign, but for this test we will be waiving the signed consent requirement. The

test administrator will however inform the participant that we are testing the

functionality of the application, not the participant themselves.

2. Testing: The participant will then be asked to complete three tasks using the

paper prototypes. The test administrator will describe the task while another

team member will physically manipulate the prototype to respond to the

participants actions. As the participant presses the buttons on the prototype

they will be asked to think out loud, sharing any immediate reactions with

the administrator. Other members of the testing team will make observations

and record the participants comments while performing the test, noting any

areas of difficulty for the participant while completing the task. The task will

be considered complete when the participant reaches the final goal screen or

if the participant fails to reach the goal screen within 5 minutes. The total

testing time should not exceed 30-45 minutes per participant.

3. Post Test Questions: After each task the participant will be asked a series

of questions to gage their reaction to the task. The questions will take the

form of a questionnaire that will be completed and returned to the test

administrator. Then upon completion of all three tests a final questionnaire

will be given to gage overall application performance. This information will be

compiled with the administrator and test observer notes and analyzed to find

areas of improvement in the application.

4. Debriefing: Upon completion of the testing and question, the participant will

be asked if they have any questions or concerns about the test. If there are

none or when they are answered the participant will be thanked and told they

are free to leave.

Test Script

NOTE:Script is written in a conversational style. Its not necessary to read it verbatim,

but will help the moderator to keep the tone of the interview casual.

Session Introduction (5 minutes)

Hi, welcome and thank you for agreeing to take part in our research study. My name is

(xxxx), and this is (xxxx), who will be observing what we are doing today.

During this session Ill be reading from a script to make sure my instructions to every-

one who participates in our study are the same.

We are here today to learn how users interact with the iPhone application GoBaby and

how well this product works for its intended audience, users like you. We have brought

here to see what you think of the app: what seems to work for you, what doesn t, and so

on. The application is currently in an early stage of development, so not everything you

are going to see will work right.

This session should take about 30-35 minutes.

We are going to be videotaping what happens during this session to help us in the

analysis process. It is primarily so I dont have to sit here and take notes and allow me

to focus on talking to you. The video will be shared with our development team mem-

bers and me. It is strictly for research and not for public broadcast or publicity or promo-

tion.

We would like to start by having your signed consent form, please? Thanks. [If partici-

pant does not have a signed consent form, give one to participant and have her/him re-

view and sign now]

Please know that we are not testing you in any way, and there is no such thing as a

wrong answer or a wrong choice. Your participation in this study helps us understand

what works or doesnt work about the site.

During this session, I will ask you to do a variety of things using our mock iPhone appli-

cation and will observe you while you do them. As you do these things, please try to do

whatever you would normally do.

Please try to think out loud while you are working. Just tell me what is going through

your mind. Every thought, question or comments is very important for us. I need to know

exactly what you think, not what you think I want to hear.

Now Id like to read you a statement of informed consent, it set out your rights as a per-

son who is participating in this kind of research.

As a participant in this research:

- You may stop at any time

- You may ask questions at any time

- You may leave at any time

- There is no deception involved

- Your answers are kept confidential

Any questions before we begin?

Lets start!

Evaluation Instructions (1 minutes)

The most important thing to remember is that you are testing the interface, the interface

is not testing you. There is absolutely nothing that you can do wrong. If anything seemswrong or weird, or especially confusing, its not your fault. However, wed like to know

about it. So please tell us whenever anything isnt working for you, or when something

does works for you, when you find a feature you like. Since this application is being de-

signed for people like you, we really want to know exactly what you is working or not

working for you.

Please remember to narrate what you are doing, kind of like a play-by-play, telling me

what you are doing it and why you are doing it.

Any questions?
