What design process has the phases Discover, Design, Develop, and Test?

• A. Agile Design
• B. Waterfall Design
• C. User-Centered Design
• D. Rapid Prototyping

Answer: (A)

Iterative, feedback-driven design cycles are a hallmark of Agile design. In this approach, work is organized into short iterations (sprints) where the team continuously revisits what users need (discover), outlines and plans solutions (design), builds those solutions (develop), and checks them through testing to ensure they meet goals and catch issues early. This cycle repeats, allowing learning from each iteration to inform the next, and enabling quick adaptation to changing requirements or new insights.

Waterfall design, by contrast, follows a linear sequence of phases (requirements, design, implementation, verification) with little or no backtracking, so late feedback isn’t incorporated as readily. User-centered design emphasizes involving users throughout the process and focusing on usability, but it’s a philosophy rather than a fixed four-phase lifecycle. Rapid prototyping centers on creating fast models to gather quick feedback, which can occur within agile cycles but doesn’t define a four-phase process on its own.
