Abstract
Requirements management is essential to the success of any project or product. Currently, requirements derived from users’ needs are often document-centric and expressed in textual statements. Conventional requirements management techniques, although widely used, are known to have various shortcomings. A model-based systems engineering (MBSE) approach to requirements management, using models to capture and represent system requirements, has emerged with promise. This thesis explored the application of MBSE to requirements management with the goal of achieving improved communications, increased reusability, and better traceability. A model was created to transform a sample set of text-based requirements into a model-based representation. From this model, an evaluation of its effectiveness was conducted based on the performance metrics defined. Results showed that an MBSE approach had fulfilled the measures of effectiveness and met the goal of improving requirements management. However, for the successful implementation of MBSE on requirements management, there are hurdles to overcome and future work to be explored.
