Web-enabled mobile phone growth

• 25% of mobile web subscribers in the US are mobile-only.

• In North America 3G handset penetration was 38% in 2009, and is projected to be 74% in 2014.

• There are 65 million text- and web-enabled phones in the US.

Terminology

• Mobile application vs. mobile web applicationo A mobile application is a "rich client" o A mobile web application is a web application

optimized for mobile devices• Desktop vs. Mobile

o A desktop site is a traditional websiteo A mobile site is optimized for small screens and

low bandwidth

• SunPass.com 12 years old

• Originally released as an outsourced ColdFusion site

• Brought in-house and rewritten in Java in August 2010 as an exact duplicate of the ColdFusion site

History and Motivation (Part I)

• Updated in December 2010 with a new look and feel, including Wizards for complex account operations

• Used external web design firm because there were no in-house design resources

History and Motivation (Part II)

History and Motivation (Part III)

• SunPass.com access logs show 255,640,407 hits for March 2011

• SunPass.com had 49,516 credit card transactions totalling $8,129,472 for March 2011

• The tollbyplate.com violation document payment website handles an additional $500,000 per month

Based on the size of the mobile market and the activity on the SunPass website, management

decided they wanted a mobile website.

NOW!

Mobile Design Principles

• We are not mobile experts• Covered in Firtman’s Programming the Mobile Web

and at Code Camp seminar • Three types of mobile device: Web,

medium, and dumb phone• Simplicity• Progressive enhancement • Device detection so users are routed to correct

version of site

Requirements

• Mapped every flow before start of work

• Selected subset of desktop functionality

• Initial mockups on paper• Next step was simple

HTML mockups

Add/Update Credit Card CC Confirm ScreenInfo validated Success Screen

Requirements (cont’d)

• Next we developed headers and footers

• At the final signoff meeting we presented complete site mocked up with clickable static pages

Experimenting with graphics• Once functionality was

approved, we called in a design firm

• Resulting pages looked great but weren’t quite right for mobile

• Header too large• Extraneous graphics• No space for

header/footer navigation

Requirements Complete

• Actually got to follow the ideal requirements/development process

• Or did we??

Scheduling

• Three options• Based on the mockups• Management chose the

middle option• Oh yeah – plus the

mobile document payment site

Scheduling Formula:

S x P = S

M

S = Schedule Length P = Developer Padding M = Management Truncation

Design

• Decided to use existing structure:• Struts2 and Tiles framework• SunToll web service framework

• HTML/web service strategy for security and reuse

Tiers

Development Tools

• Eclipse, JBoss, Solaris• Tiles• Subversion (this was huge

for team development)• WURFL (not Danny Wuerffel!)

WURFL

• WURFL is an XML configuration file with data on many mobile devices

• Wireless Universal Resource File• Checks User-Agent tag against 4000-entry

database to determine device capabilities• Device information includes screen size,

pointer type, JavaScript support, OS• Java API provides access to the WURFL data

Surprise! (¡Que lastima!)

• Additional requirements for Spanish

• Use of text tags and resource bundles for i18n

• Piggybacked on existing Spanish initiative for outsourced translation

Mobile Testing

• No emulators (except Android)• Firefox plus User Agent Header add-on• No crowdsourcing• Firewall exposure for physical devices• HP Quality Center with traditional test cases, cycles • Adapted many existing test cases from desktop site• Testing overlapped development, three cycles• Native Spanish speakers from the call center to do

the Spanish QA in a focus-group format

Deployment

• Soft launch• Enterprise configuration• Web statistics (User-Agent)• So easy a Labrador could do it (almost)!

Enterprise Environment Configuration

Summary

Successful launch!

A major factor in our success was:High availability of the development environment to the business users during the development process, with frequent updates and lots of opportunity for feedback
