Software Requirements Specification
What it actually means
The specification of what a software item must do — functional behavior, interfaces, performance, and the qualification requirements to prove it. In DoD lineage it's the spec for a CSCI; in any lineage, it's where requirements-writing discipline (unambiguous, verifiable, singular) earns its keep.
