Measurement of Actor External Dependencies in GRL Models.
Jameleddine Hassine, Mohammad Alshayeb · 2014
Abstract. Goal models represent interests, intentions, and strategies of different stakeholders in early requirements engineering. When captur-ing requirements of socio-technical systems, goal models evolve quickly to become large and complex. Hence, understanding and maintaining such goal models become more challenging. Software engineering metric-based approaches have shown good potential in measuring software designs. In this paper, we propose a structural metric to measure actor external de-pendencies in GRL (Goal-oriented Requirement Language) models. We illustrate our approach by applying our metric to a goal model describing undergraduate students ’ involvement in research activities. 1
