功能分析系统技术（FAST）

Function Analysis System Technique (FAST) is a structured methodology used in product design and innovation to identify and analyze the functions of a product or system. It facilitates a clear understanding of how each function contributes to the overall goals and objectives, enabling teams to prioritize features and optimize design processes. By visually mapping out functions and their relationships, FAST enhances communication among stakeholders and drives more effective decision-making throughout the research and production phases.
