Effective Requirements Generation: Synchronizing Early Verification & Validation, Methods and Method Selection Criteria

This paper presents a framework that guides the requirements engineer in the implementation and execution of an effective requirements generation process. We achieve this goal by providing a well-defined requirements engineering model that includes verification and validation (V&V), and analysis. In addition, we identify focused activity objectives and map popular methods to lower-level activities, and define a criterion based process for optimizing method selection for attendant activities. Our model, unlike other models, addresses the complete requirements generation process and consists of activities defined at more adequate levels of abstraction. Furthermore, our model also incorporates a unique approach to V&V that enhances quality and reduces the cost of generating requirements. Additionally, activity objectives are identified and explicitly stated not implied as in the current models. Activity objectives are crucial because they drive the selection of methods for each activity. To assist in the selection of an appropriate set of methods, we have mapped commonly used methods to activities based on
