Which term denotes a change made to enhance performance or fix issues in a design?

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

Answer: (C)

Making a change to a design to improve how it works or to fix problems is called a modification. In engineering practice, once testing or user feedback highlights issues, engineers alter the design—whether by changing a part, adjusting dimensions, switching materials, or tweaking the geometry—to boost performance or resolve faults. This term specifically captures the act of making those direct changes to the design itself, rather than simply revisiting the process (iteration), describing improvements in general (enhancement), or confirming the design works (verification). For example, if a component is prone to failing under load, a modification might involve resizing it or choosing a stronger material to prevent that failure.
