Why Do MBSE

• MBSE enables the systems engineer to: • Cope with complexity • Avoid omissions • Avoid invalid assumptions • Integrated consistency and completeness checks • Traceability to identify potential impact of change

• Automatic, integrated document and view generation (specifications and design documents, diagrams [including SysML], ad-hoc reports) • Information exists exactly once and referenced many times • Expose entire design model to all stakeholders Allow SE’s to deal with large volumes of data, quickly and efficiently.

It is not hard to know when System Engineering fails, because when  something important goes wrong it usually makes the news fast. ‐ INCOSE

Not Doing MBSE Systems Engineering • Cost Growth • Schedule Delays • Quality Deficiencies • Inconsistency • Failure to Achieve • Architectures, • Seamless Upgradeability, • Modularity • Non Retrievable Design History

There is never enough time to do a job right the first time, but there always  seems to be enough time to do the job again
