A Quantitative ERRC Analysis Method via Requirements Cost Estimation

Value-based requirements engineering process, called the ViRE(Value-Innovative Requirement Engineering) was suggested to create an uncontested market using ERRC(Eliminate, Reduce, Raise, Create) requirements analysis. But ViRE did not provides a quantitative data analysis method for ERRC decision so as to make objective decisions for customers. In this paper, to solve this problem, we suggest a quantitative ERRC analysis by estimating requirements cost. Our method defines user requirements and decides their weight. Then, it makes quality level table for all the identified requirements and function modules and estimate implementation cost based on their quality levels. Finally, assess each requirements's impact and then evaluate ERRC value. We could get the more objective ERRC values by evaluate the requirement weight, functional module weight, and implementation cost. And we proved the efficiency of our model by a case study, smart student ID system.
