Model-Based Systems Engineering (MBSE) is a systems engineering process paradigm that emphasizes the application of rigorous architecture modeling principles and best practices to systems engineering activities throughout the system development life cycle (SDLC).
These systems engineering activities include, but are not limited to, requirements analysis, functional analysis, performance analysis, system design, trade studies, system architecture specification and system Verification & Validation (V&V).
Models are at the heart of science and engineering. Model-based approaches to software development and systems engineering use technologies to include graphical modeling languages, such as the Systems Modeling Language (SML) that support system design and analysis through machine readable models
According to the Object Management Group (OMG), the most significant motivator for users selecting MBSE is to reduce downstream defects and improve the quality of both requirements and designs.
Other high ranking motivators include developing systems concepts and facilitating better communications among team members.
MBSE and Fast Learning Cycles
MBSE is now favored by many organizations because it supports fast learning cycles and helps mitigate risks early in the product life cycle. Models facilitate early learning by testing and validating specific system characteristics, properties or behaviors, enabling fast feedback on design decisions.
As the name implies, MBSE features models as the primary data source. Developing a set of related system models help define, design and document a system under development. These models provide an efficient way to explore, update and communicate system aspects to stakeholders, while significantly reducing or eliminating dependence on traditional documents.
Models and learning cycles Models can predict performance (response time, reliability) or physical properties (heat, radiation, strength). They explore design alternatives for user experience or response to an external stimulus.
But models don’t only explore technical design alternatives. The practices of design thinking and user-centered design are synergistic with MBSE and help validate assumptions sooner.
