What is hardware and software requirements?

System requirements are the required specifications a device must have in order to use certain hardware or software.

For example, a computer may require a specific I/O port to work with a peripheral device.

Typical system requirements for a software program include: Operating system.

What is correct requirements?

Correctness in requirements is simply about getting it right. We wrote previously about how to apply use cases to creating correct requirements. Writing requirements correctly is as much about getting accurate information as it is about accurately documenting the information we gather.

What is a FRD?

The functional requirements document (FRD) is a formal statement of an application’s functional requirements. It serves the same purpose as a contract. The developers agree to provide the capabilities specified. The client agrees to find the product satisfactory if it provides the capabilities specified in the FRD.

What are the four major steps of requirements specification?
