What is a functional requirement represented as in a use case?
As the name implies, Functional requirements describe the functionality of the product. They describe exactly what tasks the software must perform. Functional requirements define the scope of the system, the product boundaries, and its connections to adjacent systems.
What is the difference between requirements and use cases?
A requirement is typically a general statement, whereas a use case is typically a specific statement implied or derived from the requirement. A requirement may map to multiple use cases. A scenario might be a set of background assumptions that put a use case in context, or it might be grouping of use cases.
Why use cases are essential for functional requirements?
This is because a use case, via the main and alternate flows, shows how a user interacts with a system in order to achieve a desired result. That’s exactly the purpose of a “functional requirement” to describe the functions and behaviors that a system is or should be capable of.
What is the relationship between use cases and functional requirements?
Use cases approach is considered a more efficient means of collecting essential requirements, whereas functional requirements approach ensures a complete specification that can then filter out redundancies, overlaps, and unwanted features.
