Goal-Orientation provides a rich framework to reason about systems at Requirements Engineering (RE) time, at least using some quantitative forms of reasoning on a goal structure. This paper focuses on the assessment of the satisfaction level of requirements and related goals which has to be measured at run-time and possibly involves some multiple instantiation schemes. We propose a framework to derive such a run-time assessment from the design-time goal model and illustrate it on a real-world case study from the accessibility domain.
