Goal Oriented Requirement Engineering

Goal models have been proved to be useful to model and analyze stakeholder objectives to elicit requirements of information systems (IS). However, a goal model also needs to anticipate uncertain events (the ones with negative impact/risks) that can affect the achievement of stakeholder objectives. Therefore, my research intends to extends the goal model with other layers of analysis (namely event and treatment analysis). The Goal-Risk Framework are introduced extending Tropos goal model with 3 layers of conceptual analysis: goal, event, and treatment layer.

• Strategy layer is meant to analyze strategic interest of stakeholders.
• Event layer analyzes the impact of uncertain events to the goal layer (i.e., a risk is uncertain event with negative impact).
• Treatment layer analyzes a course of actions that are meant to treat uncertain events (e.g., mitigate risks).

This work intends to enhance the state-of-the-art Requirements Engineering Tropos methodology in order to deal with risk and its treatment during all phases of the software development process.
