Research on Symmetry Optimization of Designer Requirements and Prototyping Platform Functionality in the Context of Agile Development

Aligning designer requirements with prototyping platform functionalities remains a challenge in agile development (AD) environments, as existing tools often fail to accommodate evolving needs. This study proposes a systematic approach to optimizing prototyping platforms by bridging the gap between user needs and functional design. First, a designer requirement architecture was constructed using grounded theory, identifying three core elements: interaction needs, collaboration needs, and visualization and testing needs. The F-KANO model was used to categorize requirements, while DEMATEL was used to prioritize them based on interdependencies. Finally, quality function deployment (QFD) was used to map designer needs to functional specifications, deriving an optimization strategy. Empirical evaluation through user testing indicated notable improvements in workflow efficiency, usability, and collaboration effectiveness. This research offers a systematic framework for refining prototyping platforms in AD, improving design efficiency and UX.
