Which design approach places user satisfaction as a top priority?

• A. bottom-up design
• B. top-down design
• C. waterfall design
• D. agile design

Answer: (A)

The approach that places user satisfaction at the forefront builds from the ground up with pieces the user directly interacts with. In bottom-up design you start by creating small, usable components—such as buttons, forms, and navigation elements—that address real user tasks. By validating and refining these components first, you ensure each part delivers clear value and a smooth user experience. As these proven pieces are combined into larger features and the full interface, usability and consistency are preserved, keeping user needs central throughout the process. This emphasis on delivering usable, user-facing parts early is what makes bottom-up design well aligned with maximizing user satisfaction. Top-down focuses on overall structure first, waterfall follows a rigid sequence of phases, and agile centers on iterative delivery and continuous feedback; each has its strengths, but the bottom-up path specifically anchors satisfaction in the components users actually use.
