What is the difference between functional and non functional requirements?
Functional requirements explain how the system must work, while non functional requirements explain how the system should perform.

Does my system need non functional requirements?
To simply operate, the system does not need non functional requirements to be met. To work in a manner that the user expects, it will likely need some non functional requirements to be met.

Is performance a functional requirement?
Performance is not a functional requirement. It is considered a quality attribute, so it is a non functional requirement.

Why should I document requirements?
Documenting requirements ensures everyone is clear on what the system must do and how it must perform. Clarifying these points ensures the software engineering project can run on time and to budget and avoid disappointment.

Should I include diagrams in a functional requirements document?
It is not 100% essential to include diagrams in a functional requirements document. However, diagrams can help improve understanding of how a system works so can be very useful for clarification purposes. Diagrams are especially useful for explaining processes.
