User Experience Evolution Lifecycle Framework

Perceptions of quality from both designers and user s perspective have now stretched beyond the tradition al usability, incorporating abstract and subjective concepts. Thi s has led to a shift in human computer interaction research communities’ focus; a shift that focuses on achieving user experience (UX) by n ot o ly fulfilling conventional usability needs but also those that go beyond them. The term UX, although widely spread and given significa nt importance, lacks consensus in its unified definition. In this paper, we survey various UX definitions and modeling frameworks and examine them as the foundation for proposing a UX evolution life cycle framework for understanding UX in detail. In the proposed fra mework we identify the building blocks of UX and discuss how UX evolve s in various phases. The framework can be used as a tool to unde rstand experience requirements and evaluate them, resulting in better UX design and hence improved user satisfaction.
