Is login a functional requirement?
A login is a function or specific behavior. You either have a login capability or you don’t. As such, as requirement, it would be a functional requirement. Performance, say, of login, is a non-functional requirement: a judgement of the quality of the implementation (rather than a feature is present/absent).
What are the elements of requirements analysis?
The analysis model is organized into four elements—scenario-based, flow-oriented, class-based, and behavioral. Requirement Analysis results in the specification of software’s operational characteristics; indicates software’s interface with other system element; and establishes constraints that software must need.
What do good requirements look like?
A good requirement states something that is necessary, verifiable, and attainable. Even if it is verifiable and attainable, and eloquently written, if it is not necessary, it is not a good requirement. If a requirement is not attainable, there is little point in writing it. A good requirement should be clearly stated.
What are the 5 types of requirements models?
Requirements modeling comprises several stages, or ‘patterns’: scenario-based modeling, data modeling, flow-oriented modeling, class-based modeling and behavioral modeling. Each of these stages/patterns examines the same problem from a different perspective.
