How do you gather non-functional requirements?

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 are non-functional requirements and how do you capture them?

Functional vs Non Functional Requirements

Functional Requirements Non Functional Requirements
It is captured in use case. It is captured as a quality attribute.

Why do we need non-functional requirements?

The nonfunctional requirements ensure the software system follow legal and compliance rules. They ensure the reliability, availability, and performance of the software system. They ensure good user experience and ease of operating the software. They help in formulating security policy of the software system.

How do non-functional requirements affect the design of a system?

Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs. NFRs influence all backlogs: Team, Program, Solution, and Portfolio.
