| A structured and logical approach that serves as a foundation and starting point for conducting data analysis. |
| The reference point for models and data across the system life cycle. The authoritative source of truth provides traceability as the system evolves, capturing historical knowledge and connecting configuration controlled versions of models and data. |
| The quantitative or qualitative characteristics of a data element. |
| An artifact produced within, or generated from, the digital engineering ecosystem. These artifacts provide data for alternative views to visualize, communicate, and deliver data, information, and knowledge to stakeholders. |
| The ability to develop, validate, use, curate, and maintain technically accurate digital systems and models of systems, subsystems, and their components, at the appropriate level of fidelity to ensure test activities adequately simulate the environment in which a system will be deployed. |
| A model that is digitally represented. |
| The communication framework that allows a connected data flow and integrated view of an asset’s data (i.e., its Digital Twin) throughout its lifecycle across traditionally siloed functional perspectives. |
| A digital twin is a virtual representation of real-world entities and processes, synchronized at a specified frequency and fidelity. |
| Systems Engineering is a transdisciplinary and integrative approach to enable the successful realization, use, and retirement of engineered systems, using systems principles and concepts, and scientific, technological, and management methods. |
| An acquisition and design strategy consisting of a technical architecture that uses system interfaces compliant with widely supported and consensus-based standards (if available and suitable). The strategy supports a modular, loosely coupled and highly cohesive system structure that allows severable system components at the appropriate level to be incrementally added, removed, or replaced throughout the life cycle of a system platform to afford opportunities for enhanced competition and innovation. |
