As you know we have traditional requirement engineering models and techniques developed and used since several years. With technological advancements all around the globe, requirement engineering field also progressed, and a new model is developed named as Goal-Oriented Requirement Engineering (GORE). GORE is increasingly being popular day-by-day. You are required to discuss it’s significance and usefulness in the area of requirements engineering.

Goal-Oriented Requirement Engineering (GORE) is a model that focuses on capturing and modeling the goals and objectives of stakeholders in the requirements engineering process. It aims to systematically analyze the goals, assess conflicting or competing goals, and derive requirements to satisfy these goals. GORE has emerged in response to the limitations of traditional requirement engineering models and techniques.
The significance of GORE lies in its ability to address the challenges faced by traditional approaches. Here are some key aspects highlighting its usefulness in the area of requirements engineering:
1. Stakeholder-centric approach: GORE emphasizes the importance of understanding stakeholders' goals and objectives. By involving stakeholders early in the process, GORE ensures that their perspectives are considered, resulting in more accurate and relevant requirements.
2. Goal modeling techniques: GORE utilizes goal modeling techniques (such as the Goal Structuring Notation) to represent and reason about goals. These techniques provide a structured way to express, analyze, and prioritize goals, enabling a better understanding of the desired system behavior.
3. Goal refinement and prioritization: GORE facilitates the refinement and prioritization of goals. Through systematic analysis, conflicting or competing goals can be identified and resolved, ensuring that the resulting requirements align with the overall system goals.
4. Traceability and impact analysis: GORE places a strong emphasis on traceability, enabling the mapping of goals to requirements and vice versa. This traceability allows for impact analysis, ensuring that any changes to goals or requirements are properly assessed and their implications understood.
5. Flexibility and adaptability: GORE acknowledges that goals and requirements evolve over the course of a project. It provides mechanisms to handle goal change, which is particularly crucial in dynamic environments, where requirements may need to be modified to accommodate changing business needs.
6. Alignment with business value: GORE helps establish a clear and traceable link between the identified goals and the business value they represent. This facilitates decision-making processes, as stakeholders can easily assess the impact of requirements on achieving their desired business outcomes.
In conclusion, GORE offers significant benefits in the area of requirements engineering. Its stakeholder-centric approach, goal modeling techniques, and emphasis on traceability and impact analysis contribute to improved requirement elicitation, analysis, and management. By using GORE, practitioners can address the challenges associated with traditional models and techniques, leading to better alignment between system requirements and stakeholder goals.
