A Systematic Mapping Study of Empirical Research in GORE

Goal Oriented Requirements Engineering (GORE) has the potential to fulfill customer’s needs. It is an emergent field in requirements engineering (RE) because it helps to achieve the intended objectives of the system under consideration. A large number of Conferences and Journals have reported GORE work regarding different techniques, tools, frameworks, and methods with various processes. However, there is little effort to aggregate GORE existing empirical work, identify knowledge gaps, trends, and patterns by using an unbiased, comprehensive and systematic methodology. Therefore, there is a need to evaluate GORE empirical research to show its affluence. We conducted Systematic Mapping Study (SMS) to analyze empirical research in GORE. An analysis on extracted data showed the great increase of GORE empirical work in the year 2012 and the most focused area is Requirements Analysis (63%), and Elicitation (20%) while the Modeling (70%) is a trendy concept in Requirements Analysis. The most used research method in GORE empirical studies was the experiment. Our study did not find any empirical work in the GORE area of Validation and Verification. A large percentage of studies presented methods as the output of research and validated these methods empirically. To develop the reliability and integrity of research outcomes, the researchers need to perform evaluative empirical research. The practitioners are required to share their experiences of using various modeling tools and techniques the community.
