In the design process, what is the process called when you go through the steps again to refine a solution after testing?

• A. Revision
• B. Development
• C. Verification
• D. Iteration

Answer: (D)

The process is about repeating the design steps to improve the solution after you’ve tested it, using the results as feedback to refine the design. This looping, where testing informs changes and you go through planning, prototyping, testing, and evaluation again, is what helps you move toward a better, more ready-to-use solution—adjusting factors like performance, costs, and safety with each cycle. That flexible, repeating cycle is called iteration. Other terms describe different parts of the process but not the ongoing loop after testing. Revision focuses on making edits to a design, but it doesn’t specifically imply a repeated testing-and-refinement cycle. Development is the broad creation process from idea to final product, not the repeated refinement step. Verification is about checking that requirements are met, typically at a point in time rather than a continuing loop of improvement.
