2 MBSE Definition Model-based systems engineering (MBSE) is the formalized application of modeling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases. INCOSE SE Vision 2020 (INCOSE-TP ), Sept 2007 MBSE is SE 2 12/7/2017

3 Current Practice to Future Practice Today: System specification and design data related through documents Future: Shared system model with multiple views, and connected to discipline models Source: Jet Propulsion Laboratory 3 12/7/2017

10 SysML Background SysML v1 adopted in 2006 Continued evolution to address user and vendor needs SysML v1.5: current version SysML v1.6: in process Facilitated awareness and adoption of MBSE Much learned from applications of MBSE using SysML Goal: Develop next generation of SysML to support MBSE over next 10+ years

11 SysML v2 Objectives Facilitate increased adoption and effectiveness of MBSE over SysML v1 through enhanced: Precision & expressiveness Consistency and integration among the language concepts Interoperability with other engineering models and tools Usability by model developers and consumers Refer to eleven (11) Statement of Needs From August 2015 INCOSE INSIGHT Evolving SysML and the System Modeling Environment to Support MBSE
