Requirements Models at Design and Runtime

Requirements Models at Design and Runtime Prof. John Mylopoulos University of Trento – Italy

We review the history of requirements models and conclude that a goal-oriented perspective offers a suitable abstraction for requirements analysis. We then sketch some of the desirable features (... "requirements") of design-time and runtime requirements models and draw conclusions about their similarities and differences. We also stake positions on the nature of modelling languages in general, and requirements modelling languages in particular.
