Flexible, lightweight requirements modeling with Flexisketch

Early stage requirements models are often documented using paper and pencil-based approaches. In our current research, we are exploring lightweight modeling tools and approaches that could provide a beneficial alternative. We have developed the FlexiSketch tool prototype which combines support for free-form sketching with lightweight metamodeling capabilities. This creates the possibility for an automatic transcription of the documented information in later modeling stages. The tool is designed to be used on tablet devices.
