Abstract

The goal graph is used to decompose goals in Goal Oriented Requirements Engineering. It is not clear how to validate global optimality of goal graphs. In this paper, the goal algebra is proposed to formalize goal decomposition and provide graph interpretation for the goal algebra. The proposed method can reduce redundant goals and then ensure the global optimality of goal graphs using the goal dependency.
