The document discusses the concept of design flow, which refers to the structured series of steps and processes that designers follow to create effective solutions. It outlines the key stages in the design process, including research, ideation, prototyping, testing, and refinement, and how they are interconnected. Maintaining a consistent design flow streamlines the process, ensures steps are not overlooked, and allows for data-driven improvements. The research phase involves understanding user needs through methods like interviews and analysis. Ideation encourages creative brainstorming, while prototyping makes ideas tangible. Testing gathers user feedback to refine the design.
