Abstract
Goal-oriented models have become a consolidated type of
artefact in various software and knowledge engineering
activities. Several languages exist for representing such type of
models but there is a lack of associated methodologies for
guiding their construction up to the necessary level of detail. In
this paper we present RiSD, a methodology for building
Strategic Dependency (SD) models in the i* notation. RiSD is
defined in a prescriptive way to reduce uncertainness when
constructing the model. RiSD also tackles two fundamental
issues: on the one hand, it tends to reduce the average size of
the resulting models and, on the other hand, it allows including
some traceability relationships in the resulting models. As a
result, we may say that RiSD increases the understandability of
goal-oriented models whilst improving all construction.
