Here’s a challenge for the requirements modelling experts. I’ve phrased it as an exam question for my graduate course on requirements engineering (the course is on hiatus, which is lucky, because it would be a long exam…):
Q: The governments of all the nations on a small blue planet want to fix a problem with the way their reliance on fossil fuels is altering the planet’s climate. Draw a goal model (using any appropriate goal modeling notation) showing the key stakeholders, their interdependencies, and their goals. Be sure to show how the set of solutions they are considering contribute to satisfying their goals. The attached documents may be useful in answering this question: (a) A outline of the top level goals; (b) A description of the available solutions, characterized as a set of Stabilization Wedges; (c) A domain expert’s view of the feasbility of the solutions.
Update: Someone’s done the initial identification of actors already.
