Abstract. This paper presents a simple logic­model
semantics for Software Cost Reduction (SCR) soft­
ware requirements. Such a semantics enables model­
checking of native SCR requirements and obviates
the need to transform the requirements for analysis.
The paper also proposes modal­logic abbreviations for
expressing conditioned events in temporal­logic for­
mulae. The Symbolic Model Verifier (SMV) is used
to verify that an SCR requirements specification en­
forces desired global requirements, expressed as for­
mulae in the enhanced logic. The properties of a small
system (an automobile cruise control system) are ver­
ified, including an invariant property that could not
be verified previously. The paper concludes with a
discussion of how other requirements notations for
