Consider the NFR Framework described in Section 12.3.7. Draw a QOC model that is equivalent to the goal graph depicted in Figure 12-12. Discuss the respective advantage and disadvantages of QOC and the NFR Framework for representing rationale during requirements.

Figure 12-2 depicts a QOC model equivalent to the goal graph. The advantages of the NFR Framework over QOC are
that
• goals (questions) are represented as an AND-OR refinement a hierarchy
• the satisfied goals for a given option are more easily visible
