System requirements engineers must handle functional and non-functional needs concurrently.
System requirements engineers must handle functional and non-functional needs concurrently.
Functional requirements and non-functional requirements are two types of requirements that might be considered in the design and development of a system.
Functional requirements outlines what the system should do or the tasks it must perform. These requirements specify the features, functions, and capabilities of the system. Examples of functional requirements include:
- Enable users to build new accounts.
- Enable users to search for products by name or category.
- Provide users with the ability to purchase items utilizing a credit card.
On the other side, non-functional requirements specify how the system ought to function. These specifications outline the features or properties of the system, such as its usability, performance, and dependability. Non-functional needs include the following examples:
Reaction time ought to be under 2 seconds.
The system needs to function 99.99% of the time.
The system must be capable of supporting 1000 concurrent users.
Constraints like financial restrictions or technological limits might also be considered non-functional requirements.
Non-functional requirements define how well a system functions, functional requirements describe what the system accomplishes. While planning and creating a system to suit the demands of its users, both types of requirements must be taken into account.
