Simple design emphasizes functionality and user experience by creating a straightforward path for users to achieve their goals, often emerging from complex requirements and ideas. The process, termed "Vagueness to Clarity," involves deeply understanding the problem, which leads to a seemingly intuitive product that hides the extensive thought and iteration behind it. The design journey begins with a vague concept and, through continuous questioning and collaboration with engineers, transitions into a complex understanding that can feel overwhelming. Overcoming this complexity involves prototyping and simplifying, where the focus shifts to removing non-essential elements to ensure a frictionless user experience. This iterative process not only clarifies the design but also results in a better product that delights users by making it appear effortless and intuitive.
