What is the difference between functional requirements and nonfunctional requirements?
Just so, what are examples of functional requirements?
Typical functional requirements include:
- Business Rules.
- Transaction corrections, adjustments and cancellations.
- Administrative functions.
- Authorization levels.
- Audit Tracking.
- External Interfaces.
- Certification Requirements.
Likewise, what is meant by functional requirements? In software engineering and systems engineering, a functional requirement defines a function of a system or its component, where a function is described as a specification of behavior between outputs and inputs. As defined in requirements engineering, functional requirements specify particular results of a system.
Also know, what are examples of non functional requirements?
A non-functional requirement defines the performance attribute of a software system. Types of Non-functional requirement are Scalability Capacity, Availability, Reliability, Recoverability, Data Integrity, etc. Example of Non Functional Requirement is Employees never allowed to update their salary information.
Who defines non functional requirements?
In systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviors. They are contrasted with functional requirements that define specific behavior or functions.
