How do you write a non functional requirement for a project?
How do you gather non-functional requirements?
To collect the requirement, analyse them from performance testing perspective and finalise the quantitative NFRs; all these steps fall under the NFR gathering phase of PTLC (Performance Test Life Cycle). All the requirements are documented, categorized and concluded in the Non-Functional Requirement Document.
What is functional and non-functional requirements in SRS?
A functional requirement defines a system or its component. A non-functional requirement defines the quality attribute of a software system. It specifies “What should the software system do?” It places constraints on “How should the software system fulfill the functional requirements?”
