Today, many organizations are adopting aspects of Model Based Systems Engineering (MBSE) to improve their systems engineering practice, particularly since MBSE was introduced in the INCOSE Systems Engineering Vision 2020 in 2007.
As with any organizational change, this must be approached strategically to grow this capability and learn from their experiences.
Like other engineering disciplines, the transition of systems engineering to a model-based discipline is broadly recognized as essential to meet the challenges associated with increasing system complexity and achieving the productivity and quality improvements.
The object of Model Based Systems Engineering is to build a well-defined model of the product design that is complete and consistent and accurately represents truth. This allows for analysis and review and test on the model.
Consequently, the benefits are immense such as cost is reduced and development time is reduced and quality is improved. It is also much easier to try alternate designs.
Additionally, in an MBSE approach requirements can be incorporated into the model, as can test plans and the like. The tools can be used to support reviews directly without producing piles of documents.
If you do want to build documents, you can to varying degrees generate the documents directly from the model. When the model changes, just regenerate the documents.
Although MBSE does not dictate any specific process, any MBSE process should cover four systems-engineering domains:
- Requirements/Capabilities
- Behavior
- Architecture/Structure
- Verification and Validation
The modeling language that compliments MSBE is the OMG Systems Modeling Language (SysML). SysML is a general-purpose graphical modeling language for specifying, analyzing, designing, and verifying complex systems that may include hardware, software, information, personnel, procedures and facilities.
In particular, the language provides graphical representations with a semantic foundation for modeling system requirements, behavior, structure and parametrics, which is used to integrate with other engineering analysis models.
