    2. 2 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE

    3. 3 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE DEFINITIONS Complexity: No single person can comprehend and manage the whole system Systems Engineering: Decision-making processes associated with defining, developing and fielding complex systems Architecture: Design intent with respect to a viewpoint Logical Architecture Physical Architecture Technical Architecture

    4. 4 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE WHAT IS A MODEL? An abstraction of reality designed to convey information Defined with respect to some aspect of structure or behavior Necessarily incomplete and approximate A model of the system is NOT the system CLASSES OF MODELS Descriptive Model: Approximation of what is Prescriptive Model: Approximation of what is intended be Predictive Model: Approximation of emergent behavior It takes many models to adequately describe a complex system.

    5. 5 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE THE 4 PILLARS OF SYSTEMS ENGINEERING Requirements: VOC > Use Cases / MOEs / MOPs Architecture (Structure): Configuration / Interfaces Logical, Physical, and Technological Domains System Context Behavior: Process ( as designed) Emergence: Intended vs. Unintended Behaviors from Predictive Model Parametrics: Formal relationships and constraints Tied to architecture and/or Processes Variables for trades and optimization

    6. 6 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE WHAT’S DIFFERENT ABOUT MODEL BASED SE? Haven’t we always used models to specify our systems? Text based documents are models Drawings and diagrams are models Model Based implies: Only one definition can exist for any element of the model Unique representation in model repository Any number of presentations are possible Model is integrated Relationships between elements are themselves model elements Modeling language is based upon a generalized Metamodel

    7. 7 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE TRADITIONAL (DOCUMENT CENTRIC) SE Using 4 Pillars of Systems Engineering

    8. 8 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE MODEL BASED SE: INTEGRATED

    9. 9 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE 4 Pillars Integrated Models via SysML (Ron Williamson)

    10. 10 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE AN ANALOGY TO MBSE: MECHANICAL DESIGN Mechanical Design Models Then: 2D or 3D wireframe Now: Solids Modeling Properties Then: Assigned in writing in blocks or notes or instructions Now: Build into model Changes: Then: Must work through every drawing sheet affected by the modified component Now: Change the solid model, automatically reflect it throughout

    11. 11 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE COMPARE TRADITIONAL TO MODEL BASED SE… Weaknesses of Traditional Approach: Model and Documentation are Separate Entities (De-Linked) Complex Organizational Processes Strength of Traditional Approach: Comfort Zone; Mature Processes Theoretical Strength of MBSE Approach: The Model is the Documentation Common use of OOD/OOA Possible Weaknesses of MBSE: Requires significant training and infrastructure management Risk (real or perceived) of being the first… Little experience with the method outside of technical domains This is why we are executing the MBSE Initiative

    12. 12 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE THEORETICAL VALUE OF MBSE ENHANCED COMMUNICATIONS Shared Understanding / Integrated Views REDUCED DEVELOPMENT RISK Faster Requirements Cycle / Better Cost Estimates IMPROVED QUALITY Concise Requirements / Traceability / Configuration Control INCREASED PRODUCTIVITY Faster Analysis of Design Changes / Reduced Errors / Reduced Effort ENHANCED KNOWLEDGE TRANSFER Standard Information Formats

    13. 13 INCOSE MODEL BASED SYSEMS ENGINEERING INITIATIVE INTRODUCTION TO THE MBSE INITIATIVE PURPOSE OF THE MBSE INITIATIVE Evaluate the methodology & languages (SysML, UML, etc.) Identify areas for improvement Share the knowledge across the SE community Promote the methodology if appropriate SOURCE OF THE MBSE INITIATIVE: Major initiative of INCOSE INCOSE Model Driven System Design (MDSD) Working Group INCOSE Architectures Working Group INCOSE Requirements Working Group
