Interactive Visualization for Elicitation and Validation of - PowerPoint PPT Presentation

Interactive Visualization for Elicitation and Validation of Requirements with Scenario-Based Prototyping Gregor Gabrysiak , Holger Giese, Andreas Seibel Hasso Plattner Institute, Potsdam

2 Problem Statement • validation of requirements calls for stakeholder involvement • semantic barriers of requirements models restrict feedback during the validation • overhead through translation Interactive Visualization for Elicitation and Validation Gregor Gabrysiak, Holger Giese, Andreas Seibel REV’09 of Requirements with Scenario-Based Prototyping

3 How can we fix it? • domain-specific requirements animation • leveraging formal requirements to be tangible for end users and other stakeholders • transport the modeled content back into the stakeholders’ domain of expertise Interactive Visualization for Elicitation and Validation Gregor Gabrysiak, Holger Giese, Andreas Seibel REV’09 of Requirements with Scenario-Based Prototyping

9 PROs CONs front-end with domain still “kind of unintuitive” specific animations automation can be applied currently, inconsistencies have to in the back-end be spotted and resolved manually inexpensive validation sessions infinite iteration loop possible currently, underlying models are single and multi-user modes too static Interactive Visualization for Elicitation and Validation Gregor Gabrysiak, Holger Giese, Andreas Seibel REV’09 of Requirements with Scenario-Based Prototyping

10 Validation & Next Steps • evaluation in projects together with our industrial partner, D-LABS GmbH • comparison based on the amount and kind of feedback gathered from end users • increase automation capabilities • enhance look and feel of the prototype Interactive Visualization for Elicitation and Validation Gregor Gabrysiak, Holger Giese, Andreas Seibel REV’09 of Requirements with Scenario-Based Prototyping
