Provide examples of indirect requirements.

Performance requirements: response speed, number of concurrent users, load testing.

Security requirements: authorization, authentication, data protection, compliance with security standards.

Usability requirements: intuitive interface, accessibility for different user categories, ease of learning.

Reliability requirements: uptime, fault tolerance, recovery speed after failures.

Maintainability requirements: modular code, readability, documentation, ease of making changes.
