Case studies on the application of the CORE model for requirements engineering process assessment [software engineering]

Existing requirements engineering (RE) process assessment models lack the components necessary to provide enough information about the quality of an RE process. The concept of "concern of requirement engineering" (CORE) and the assessment models proposed in our previous research provide a method and new perspectives to assess the quality of an RE process. The case studies presented in this paper provide a comprehensive view of the application of the CORE model. The advantages of using the model for RE process assessment are twofold. First, it is more flexible because the major COREs assess the main contents of the activities of an RE process. Second, the categories classified in the model allow RE process assessment based on several categories. This allows for process improvement in an incremental manner. The CORE model is part of our RE process development framework and is used to assess the quality of the RE process under development.
