Mark Brörkens

The document discusses bridging the gap between textual requirements and model-based software development, emphasizing the importance of requirements management and traceability in improving software project outcomes. It introduces the OMG Requirements Interchange Format (REQIF) and the Eclipse Requirements Modeling Framework (RMF) as tools for integrating textual requirements into development processes. The document outlines industry challenges in software project failures and presents solutions through structured requirements management practices.
