Model-Based Systems Engineering (MBSE) emphasizes the application of precise visual modeling principles and best practices throughout the System Development Life Cycle (SDLC). MBSE is compromised of a variety of different elements such as requirements analysis, validation and verification; functional analysis and allocations; performance analysis and trade studies; and system architecture specification. Using MBSE results in fewer human errors, heightened productivity, and superior design quality.
When it comes to using the Model-Based Systems Engineering (MBSE) approach, achieving the following process goals is necessary.
Architecture-Centric: The MBSE process aims to improve product development and quality by using architecture to gain confidence early in achieving system-related business and mission goals. The process also emphasizes a system architecture model as the primary work artifact throughout the System Development Life Cycle.
Full System Development Life Cycle support: In order to reduce human error, Model-Based Systems Engineering supports all phases of the SDLC. MBSE, at its core, is about bridging all of these phases in order to deliver superior results.
- System Analysis
- System Design
- System Integration
Requirements-driven & Full V&V Support: The MBSE process is driven by the requirements. Since the process must support the full SDLC requirements, it is imperative that it be able to track the process, as well as verify and validate, all functional and non-functional requirements.
Straightforward & Systematic: One of the core strengths of the MBSE process is the ability to explain the project in a straightforward and systematic manner. This eliminates confusion and makes it easy for Systems Engineers to learn and apply.
Using Open Standards: To maximize the effectiveness of the MBSE process, it is necessary to support open standards for system architecture modeling and tool usability. These open standards include, but are not limited, to the following:
- UML 2
These open standards are used to specify the System Architecture Model and to serve as a base language among Systems Engineers and others involved in the process (Software Engineers, Electrical Engineers, Mechanical Engineers, Customers, etc.).
