Subjective Requirements:
- Based on personal opinions, preferences, and feelings.
- Often qualitative and open to interpretation.
- Examples: User experience (UX) preferences, design aesthetics, user satisfaction.
Objective Requirements:
- Based on factual data, measurable criteria, and verifiable conditions.
- Often quantitative and specific.
- Examples: System performance metrics (response time), compliance with technical standards, specific functionality features.
Key Difference:
- Subjective requirements are about how something feels or appears to users, while objective requirements are about concrete, measurable outcomes or specifications.
