Which term describes a change intended to improve existing performance without starting from scratch?

• A. Enhancement
• B. Development
• C. Modification
• D. Evaluation

Answer: (C)

Changing an existing item to improve its performance without starting from scratch is called modification. It means altering the current design, components, or operating parameters to achieve better results while keeping the original base in place. This fits because you’re enhancing what already exists rather than building a new product from the ground up. If you were creating something new, that would be development. If you were just adding features or upgrades without modifying the current item, that might be described as an enhancement, but the scenario specifically centers on altering the existing thing. Evaluation is about judging or measuring performance, not making changes.
