Limitations of SysML v1
(R1) The next-generation modeling language must express the core systems engineering concepts. This requires definition of a robust data model that reflects these concepts. The requirements that drove SysML derive from the original Systems Engineering Conceptual Model, jointly developed by the INCOSE/OMG/AP233 WG requirements team. Modifications and refinements to this model will occur in light of lessons learned over the last several years, and as necessary to express the core systems engineering concepts.
2. Propose updates to draft requirements attributes and categories in current concept model for consideration to be included within SysML v2 – Bertil Muth
3. Review requirements relationships in current concept model and propose a draft taxonomy and definition of relationships for SysML v2 – Rick Steiner and Brian Selvy
4. Propose how uncertainty should be addressed in SysML v2 using the current concept model and starting with the weight requirement example (Requirements/Verification SECM Concept Diagrams, slides 7-9) - Tao Yue and Shaukat Ali
5. Propose how current concept model can support scenario based requirements using natural language starting with the behavior example (Requirements/Verification SECM Concept Diagrams, slide 12) – Tao Yue and Shaukat Ali
6. Contrast the approaches to Structured Natural Language Requirements approaches – Tao Yue and Shaukat Ali
7. Discuss Bjorn Cole feedback regarding embedding the required properties and constraints in a block. Sandy Friedenthal
8. Assess the mapping between SysML v2 concepts and ReqIF concepts, and provide recommendations for potential future alignment – Bertil Muth
9. Review the integration concepts and their relationship to the verification concepts – Brian, David
