If you are a Systems Engineer and want to improve the precision and efficiency of your communications with fellow Systems Engineers and other system and business stakeholders (e.g., Clients, Software Engineers), then you should consider using a visual modeling language standard as a lingua franca (common language). The most popular choice for MBSE applications is the SysML dialect of UML 2, which extends the UML standard for software-intensive applications so that it can be applied to Systems Engineering applications.

Here's a list of reasons why Systems Engineers may want to use a Model-Based Systems Engineering approach with a common modeling language such as SysML for their work:

• Facilitate communication among various stakeholders across the System Development Life Cycle
• Capture and manage corporate Intellectual Property related to system architectures, designs, and processes
• Compare and contrast “As Is” and “To Be” solutions
• Provide scalable structure for problem solving
• Furnish rich abstractions to manage size and complexity
• Explore multiple solutions or ideas concurrently with minimal risk
• Detect errors and omissions early in System Development Life Cycle
