Which design process includes the phases Analysis, Design, Prototyping, and Evaluation (ADP)?

• A. Waterfall Design
• B. Scenario-Based Design
• C. Agile Design
• D. Rapid Prototyping

Answer: (B)

Scenario-Based Design uses user task scenarios to guide every step of the process. You begin by understanding what users need to accomplish and in what context, which is the Analysis. Those insights then drive concrete design decisions, the Design phase. To explore and test those ideas, you create quick, tangible representations of the design through Prototyping. Finally, you involve users to evaluate how well the prototypes support the scenarios, gather feedback, and refine accordingly, which is the Evaluation phase. This clear sequence—analyzing tasks, designing around those tasks, prototyping to explore the design, and evaluating with real users against the scenarios—is why this approach aligns with the ADP naming.

Waterfall Design follows a linear path that doesn’t emphasize iterative prototyping and evaluation driven by user scenarios. Agile Design is iterative and flexible but isn’t defined by these four named phases in a fixed order. Rapid Prototyping focuses on quick prototypes and testing but doesn’t inherently center on the full, scenario-driven progression of Analysis and Design as a distinct phase sequence.
