Model‐Based Systems Engineering for Project Success: The Complete Process

Abstract

This basic tutorial identifies the elements and benefits of a complete, proven model-based system engineering process, and demonstrates its tailorability and value for project success using vignettes from an information management system and a sample System of Systems (SoS) application. The tutorial illustrates how the model-based system engineering process supports both document-driven and model-based paradigms, whether in top-down, middle-out, or reverse engineering environments. It discusses how to know when each element of the process has been completed, and how to develop and validate functional and physical architectures using executable architectures. The requirement for concurrent engineering, the onion model, and synchronization of models and data are presented. The participants will be introduced to a flexible system engineering process suitable for system development tasks across the complexity spectrum. In addition to the process description, the tutorial will include a sample solution to illustrate the recommended techniques, views, completion conditions, and products of an MBSE system development methodology. It will also include examples of the development of graphical views commonly used by practitioners of DoDAF and SysML approaches. This tutorial is focused on highlighting how the use of model-based systems engineering can meet the government requirements for delivering architecture framework products while allowing the engineering organizations (industry and government) to successfully perform the systems engineering required to develop an executable design.
