DevOps for MBSE: Continuous Quality Assessment (for Non-Deterministic System Behaviour)

Non-deterministic system behaviour challenges MBSE, particularly where deterministic testing and classical verification no longer provide sufficient evidence about model quality. This presentation argues that non-determinism must not only be modelled, but continuously assessed throughout the engineering lifecycle.
We present a DevOps for MBSE approach, that introduces triggered, configurable model pipelines for continuous quality feedback, and illustrate how this is used in industry on a daily basis to support governance. These pipelines combine automated validations, lifecycle-state monitoring, trend analysis, dashboarding with lightweight manual reviews. Such reviews can be placed where deterministic tests fall short and expert judgement is required.
The framework increases transparency about the current model state, supports earlier detection of quality issues, and enables more resilient engineering decisions for systems that include non-determinism.
