The Impact of Visual Elements and Design Principles of Design Systems on Design Decisions

This study investigates the impact of visual elements (color, typography, icons, and layout) and design principles (consistency, simplicity, reusability, and accessibility) within design systems on designers' decision-making processes. A survey of 24 interaction designers with varying levels of experience was conducted to assess how these factors influence decision consistency and efficiency. Results show that color and layout are crucial in design decisions, while consistency and simplicity enhance decision-making efficiency. Designer experience significantly affects the emphasis placed on these elements, with senior designers prioritizing color, consistency, and simplicity, and junior designers focusing on reusability. The findings highlight the need for design systems to be adaptable to different experience levels to optimize design workflows and user experience.
