This paper seeks to raise awareness on the SCR extensions derived from industry use, and discusses how an integration of Software Cost Reduction (SCR) modeling concepts address current limitations in the System Modeling Language (SysML) standard. The paper describes an integration of a formal requirement modeling approach based the SCR method with the SysML structure mechanisms providing an alt...
