3. Systems Engineering Problem Requirements are often ambiguous Separation of Specification and Design is not well understood Communication is difficult Tools are not interoperable - Models are locked to tooling and methodology See document markings on Cover Page – TES-SAVi Copyright (C) 2016

4. Paradigm Shift See document markings on Cover Page – TES-SAVi Copyright (C) 2016 Requirements DocumentsUnified Models

5. Specification Solution? CDM defines the concepts of a UoP (System) May leverage and expand on CDM to develop the Specification Model as defined in DO-331 Can lead to increased communication between Engineering groups Can implement Validation throughout the entire lifecycle See document markings on Cover Page – TES-SAVi Copyright (C) 2016

6. Methodology and Tooling Solution? A solution may lie in methodologies and technologies in MBE of systems, systems-of-systems analysis, design, development, and verification. Model with a purpose: specificity of models to optimize cross-domain communication and auto generation of artifacts, development, verification and validation Advance towards an open standard that Unifies modeling the problem and solution domains of requirements, design, verification, validation, and certification to support and order of magnitude increase in complexity of safe and secure systems.
