Q

Which is not TRUE about requirements specification?
Show answer choices

It does not provide consistent outcome of the user’s desire about the needed software product

all of the above

Imprecision in the requirements specification can lead to disputes between customers and software developers.

It is natural for a system developer to interpret an ambiguous requirement in a way that simplifies its implementation.

Q

Non-functional requirements, as the name suggests, are requirements that are not directly concerned with the specific services delivered by the system to its users. These non-functional requirements usually specify or constrain characteristics of the system as a whole. They may relate to emergent system properties such as:

Arrows represent the flow of work from one activity to another, and a solid bar indicates activity coordination.

Arrows may be annotated with guards (in square brackets) that specify when that flow is followed.

When the flow from a solid bar leads to a number of activities, these may be executed in parallel.
