4 Personas - The users



Telco Wireless Ecosystem story
Case Study Focus on four different individuals. (four persona’s each with a context scenario)
All basically accomplish the same sort of task but the experience is focused for that speciﬁc
device.
4 Context Scenarios - Eco System Story

1. A stay at home Mom which logs into the Telco website and checks here account info, like
minutes the family has used, pay her bills, compare her plan with others, see a chart of text
and minutes used.

2. A younger individual say 15 that has a “Pay as you Go” type of phone and does not have a
credit card. He wants to add more minutes to his phone so he goes to the kiosk either in
the Telco store,movie theater or mall and logs in and sees his account info and decides to
put more minutes on his phone with cash. The kiosk would have the ability to accept cash
payments. Could allow to get other things like ringtones.

3. A business road warrior while traveling needs to check his account info using the Android
App on his smart phone. He checks to see when his bill is due and even could allow him to
pay his bills, compare his plan with others, see a chart of text and minutes used.

4. A grandparent or older individual that has an iPad in place of a computer. She hops on her
iPad to check her account. She launches the iPad app which has all of her account info and
allows her to pay her bill, compare her plan with others, see a chart of text and minutes used.
Also could show some content for Help Support

Less is More
Mobile
You don't need everything on a mobile
device, its mobile and not the desktop/web

Use Aggressive Auto Completion - reduce
typing

Flatten hierarchy

Truncate interfaces



Connectivity
What happens
How does your application react when its
connected and when its not, smooth user
experience

How does it handle Notiﬁcations and
Updates



Orientation
Reorganize

How does it handle Orientation changes,
Landscape vs Portrait.

Reorganize Content or Change Content



Input
What is it?

Be aware of input methods and interactions

Touch/Multi Touch
Virtual/Physical Keyboards
Wheels
VUI - Voice User Interface
TUI - Tactile User interface
GUI - Graphical User Interface

Be aware of where the user’s hand will be
while interacting with the device



HTML5
Do I use it?
HTML5 features are incomplete and do not
provide a consistent experience across
multiple devices.

<audio/>, <video/>, and <canvas/>
are not supported equally

different platforms support different codecs
and implementations

No streaming media, only progressive
download

CSS3 Styles are not consistent or reliable

HTML5 APIs, including geolocation and
ofﬂine storage are not consistent or not
implemented

No camera / device access
