Rapid application developmentChallenges
Code re-usability
• Write once use everywhere
• Tool chain
Development supports
• Proprietary OEM architecture
• Non co-operation from major player
Derivative model
• Localization
• Maintainability
• Scalability
Solution
Tool /language
• Cross platform tool
• IDE for layout
• HTML5
• ZYPR like API for social networking
Support management
• Choice of open platform
• Platform abstraction*
Flex development
• Understand localization need
• Product line management
