Model-Based Systems Engineering (MBSE) is where the model resulting from the evolution of system requirements, design, analysis, verification and validation activities is the focus of design and manufacturing.
The object of MBSE 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.
Cost is reduced and development time is reduced and quality is improved. It is much easier to try alternate designs.
The benefit from this on the design of a single product is small, though still worth doing in many cases. The real benefit comes when designing a family of products that share some parts but are different in some ways.
The common parts of the design models can be reused for very low cost and will have very few bugs from the outset. The new parts are also easier to build because many interfaces and behaviors are already designed and debugged.
There are other benefits as well from 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.
Bottom line: All of this supports an agile development process. Review and test is continuous. You don’t have to wait for the design and build to be complete, you can test the models as they are developed and eliminate many design bugs very early in the process.
