The Object Management Group has officially published Systems Modeling Language v2.0, introducing a new KerML foundation, textual syntax for version-controlled models, and a redesigned action/part/port metamodel.
The Object Management Group has formally published SysML v2 after years of development. The new standard brings a completely redesigned textual syntax (KerML), improved support for parameterized models, and cleaner interfaces with simulation environments.
As MBSE adoption matures, programs are discovering that high-fidelity models become liabilities when teams lack the resources to maintain them. This analysis proposes a fidelity calibration framework tied to program phase and risk profile.
A survey of 340 systems engineers with SysML v2 pilot experience reveals: significant improvements in semantic consistency, mixed results on tool maturity, and an underestimated migration effort from v1 models and workflows.
A comprehensive survey of open-source MBSE tools reveals a maturing ecosystem. Capella leads in adoption, openMBEE is gaining traction in the US defense community, and the SysML v2 reference implementation (openapi-sysml) is attracting significant contributor interest.
