Software models in the Unified Modeling Language (UML) can been created or automatically reverse-engineered and used for quickly gaining structural insights into larger, legacy, or unfamiliar software. But as the size, structural complexity, and interdependencies between software components in larger systems grows, two-dimensional viewing and modeling has limitations, and new ways of visualizing larger models and numerous associated diagrams of different types are needed to intuitively convey structural and relational insights. To investigate the feasibility of using Virtual Reality (VR) to create an immersive UML-based software modeling experience, this paper contributes a VR solution concept for visualizing, navigating, modeling, and interacting with software models using UML notation. An implementation shows its feasibility while an empirical evaluation highlights its potential.
VR-EvoEA+BP
(2023)
Enterprise digitalization results in an evolving and dynamic IT landscape of digital elements, relations, knowledge, content, activities, and business processes (BPs), which are spread across disparate enterprise IT systems, repositories, and tools. To be relevant, useful, and actionable, Enterprise Architecture (EA) relies on comprehensive documentation based on underlying information corresponding to reality. Yet current diagram-centric 2D visualizations for EA and BP models are too limited in scope to express reality (intentionally simplifying), are typically static (and not kept up-to-date), and cannot express and integrate the changing complexities of the enterprise context. This misalignment with reality and a changing enterprise misinforms and constrains the context-awareness and perception of EA and BP for stakeholders, impeding analyses, management, and holistic insights into the enterprise digital reality. This paper contributes our nexus-based Virtual Reality (VR) solution concept VR-EvoEA+BP to support comprehensive enterprise context visualization in conjunction with EA and model evolution and BP mining and analysis. Portraying an organic, evolving, and dynamic enterprise while supplementing static enterprise structure depictions, our implementation demonstrates its feasibility. A case study based on enterprise analysis and BP scenarios exhibits its potential.
