What term describes changes made to improve performance or solve faults?

• A. Modification
• B. Iteration
• C. Optimization
• D. Evaluation

Answer: (A)

Changes made to improve performance or fix faults are called modifications. A modification is an actual alteration to a design, component, or process to address issues or boost how well it works—like adjusting dimensions, changing materials, or tweaking features. This differs from iteration, which is the ongoing cycle of testing and refining; the modification is the concrete change you apply during that cycle. Optimization is about getting the best possible performance, often pursued through a series of modifications, while evaluation is the act of judging how well the design performs, not the change itself. So the best term for those applied changes is modification.
