Let the Agile Coach in: Conversational AI-based Product Design Process for Agile Iterative Design

Conversational artificial intelligence-assisted product design faces challenges such as uncertainty in design quality, interaction barriers, and inefficient processes. To address these issues, this study introduces the role of agile coach within designer-AI collaboration, aiming to improve iteration efficiency and design results’ quality. We developed two implementation schemes for the agile coach, one performed by a human and the other by the AI. Results of the user experiment indicate that the existence of the agile coach significantly enhances the iteration efficiency and the design results in integrity, complexity, and feasibility. Moreover, the AI agile coach outperforms the human agile coach in improving complexity, feasibility, and iteration efficiency. This study expands the application of the agile iteration method in human-AI collaboration and provides new insights into how conversational AI can empower product design.
