Which of the following best describes a change to improve performance after testing?

• A. Enhancement
• B. Revision
• C. Modification
• D. Iteration

Answer: (C)

After testing, making a modification means you implement a concrete change to the design or component to improve how it performs. It’s about adjusting the actual product based on test results to fix issues or boost efficiency, reliability, or overall function. An enhancement would add new features or upgrade capabilities, not necessarily tied to a specific test outcome. A revision focuses more on updating plans or documentation or revisiting earlier design decisions, rather than applying a direct on‑product change. Iteration is the continuous cycle of redesign, test, and refine, which often includes modifications, but the specific change aimed at improving performance is best described as a modification.
