Which statement reflects an Appian user interface design best practice?

• A. Build full one-off interfaces.
• B. Use only one interface per app.
• C. Create and use reusable interfaces.
• D. Avoid component reuse.

Answer: (C)

Reusable interfaces are the best practice because they let you define a consistent look, layout, and user interactions once and use them across multiple screens and apps. In Appian, building modular, shareable interface components means you can standardize form controls, grids, navigation, and styling in one place. When you update that single reusable piece, every screen that uses it benefits, which keeps the user experience consistent and reduces the amount of duplicated work. This approach also makes it easier to enforce accessibility and usability standards and to adapt interfaces to different contexts by passing different data or parameters. In contrast, creating many full one-off interfaces leads to duplicated effort, higher maintenance costs, and the risk of inconsistent UX patterns. Limiting to a single interface per app stifles reuse, and avoiding component reuse undermines the efficiency and consistency that a well-architected UI should deliver.
