Which statement best describes iterative design?

Which statement best describes iterative design?

• A. A linear, step-by-step process.
• B. A circle of tests that can be moved backwards and forwards.
• C. Only used for software development.
• D. A process that never revisits earlier stages.

Answer: (B)

Iterative design is all about repeating cycles of testing and refining a product. You create a version, test it, learn from the results, and then adjust the design based on that feedback. This makes the process non-linear and flexible, because you can revisit previous decisions or stages as new information comes in, rather than marching through a fixed sequence once. The statement that best fits this idea describes iterative design as a circle of tests that can be moved backwards and forwards. It captures the ongoing loop of testing, learning, and reworking, and the ability to revert to earlier steps if the results indicate changes are needed. The other descriptions don’t fit as well. A linear, step-by-step process suggests no revisiting of earlier work, which contradicts the core looping nature. Limiting iterative design to software ignores its use in hardware, products, and systems. Saying you never revisit earlier stages directly contradicts the purpose of iteration, which relies on revisiting decisions to improve outcomes.
