Software Systems Research Centre Bournemouth UniversitySSRCAlignment projects• Process Oriented Requirements Engineering.• We use (research and consultancy) and teach these approaches.• Process models (Role Activity Diagrams) are used to model the problem domain (and thus to inform requirements).• Process models mapped to (augmented) use case specification (EDUCATOR), such that process information can be represented and retained (REBNITA). • Extended (in collaboration with NICTA- Australia) to align business strategy, context and process (B-SCP) with IT.• CIM models (as requirements) within MDA. • VIDE project provides accessible models (as part of an MDA process) – including pre-CIM in order to increase involvement of breadth of stakeholders.Software Systems Research Centre Bournemouth UniversitySSRCRole Activity DiagramsSoftware Systems Research Centre Bournemouth UniversitySSRCVIDE Project• Worth 2.95 million US dollars• 10 partners including: SAP, 2 divisions of Fraunhofer, Softeam and Rodan (tool developers).• Project overall: to make model driven development fulfil business needs.• Many perspectives including: accessibility to stakeholders (CIM), Aspects, Quality defect detection, rapid transformations (via wizards), action semantics.• BU focus specifically on accessibility of notation, particularly at the CIM level.
