Select ALL examples of non-functional requirements or properties named in the material.

### Why this is right - **Reliability** is a system property named in the material. - **Response time** is a performance-related property. - **Storage requirements** constrain system resources. ### The concept Non-functional requirements specify properties and constraints rather than a particular service. A requirement for a specific service is generally functional because it states what the system should do. ### The other options - **D. A specific service the system must provide**: This describes system behavior and is therefore functional in the material's classification. - **E. The color of the project schedule**: This is not identified as a system requirement or property. ### Terms - **Non-functional requirement**: A requirement about a system property or constraint rather than a specific service. - **Functional requirement**: A statement of a service the system should provide. ### Remember Services are functional; properties and constraints are non-functional.
