The approach is based on the semantic characterization of ORdecompositions of goals. We first show that each high-level goal can be associated with a set of concerns in response to which alternative refinements of the goal can be introduced. A text corpus relevant to the domain of discourse can be used to derive such variability concerns that are specific to the problem. In parallel, non-intentional background facts that can vary while a goal is being fulfilled are modeled. Then, a high-variability goal model is constructed aiming at responding to the predefined variability concerns completely, while non-intentional factors are used to test whether the result addresses all realistic background circumstances. We apply our approach in a study from the geriatric health care domain.
