This chapter introduces the concept of convergence in Extended Reality (XR) frameworks within the context of Model-Based Systems Engineering (MBSE). This chapter refers to the integration and alignment of various technologies, methodologies, and tools to create cohesive and immersive experiences. The convergence is driven by the need to enhance collaborative systems engineering processes, improve decision-making, and facilitate stakeholder engagement in complex system development. The convergence transforms the systems engineering landscape by providing advanced tools that facilitate collaboration, visualization, and decision-making. This integration leads to more effective complex system design and development, ultimately resulting in high-quality outcomes that meet stakeholder expectations.
