In requirements, what does 'subjective' describe?

• A. How the system is supposed to be
• B. What the system should do
• C. The performance metrics
• D. The user experience

Answer: (D)

Subjective requirements describe how a product feels to users—their perceptions, judgments, and satisfaction with using the system. This is about user experience, which varies from person to person and is not a fixed, objective measurement. In requirements, you’ll see subjective criteria like ease of use, overall satisfaction, or perceived quality, often gathered from user feedback or surveys. In contrast, objective criteria are things you can measure directly, such as response time or error rates. So describing the user experience as subjective captures that it's about how the system is perceived and experienced, not just what it does or how fast it runs.
