Towards an ontology of requirements engineering approaches

Requirements are a key factor in determining the success or failure of the system development process. Requirements engineering is a creative problem-solving process whose primary purpose is to enable researchers and practitioners to apply appropriate theories, models, techniques and tools to understand and support the requirements processes more effectively. However, there is a multitude of ways to conduct the requirements engineering process and the quality of the requirements can be greatly influenced by the approaches employed. While consensus exists that no one approach works in all situations, how do practitioners and researchers select the most relevant and appropriate approach(es)? In order to understand this, we argue that a community-based effort is required to organise the plethora of requirements engineering approaches into an ontology. Such a structure would provide an opportunity to identify gaps and to improve the interfaces between approaches. Crowdsourcing the development and validation of such an ontology would facilitate its application across different system types and application domains.
