Glossary
Quick reference terms used across our Learn section. For depth, start with Digital Engineering and SysML v2.
Digital Engineering
An approach to developing systems where machine-readable models, automation, and reproducible workflows replace or augment document-only processes.
MBSE (model-based systems engineering)
Systems engineering practices centered on formal models as the primary engineering artifacts, enabling analysis, traceability, and integration across disciplines.
MBD (model-based design)
Often used for model-based development of controls and software (e.g. simulation, code generation). Related to MBSE but not the same scope; teams may use both.
SysML v2
The OMG systems modeling language built on KerML, aimed at integrated requirements, structure, behavior, and parametrics for complex systems.
KerML
Kernel Modeling Language — the semantic and syntactic foundation on which SysML v2 is defined.
Digital thread
A connected flow of authoritative data across the lifecycle (design, build, test, operate), so decisions and artifacts stay traceable and consistent.
Digital twin
A live or periodic coupling between a virtual model and a real asset or process — used for monitoring, prediction, and optimization.
