Agile Model-Based Systems Engineering Cookbook

By: Dr. Bruce Powel Douglass

Overview of this book

Agile MBSE can help organizations manage constant change and uncertainty while continuously ensuring system correctness and meeting customers’ needs. But deploying it isn’t easy. Agile Model-Based Systems Engineering Cookbook is a little different from other MBSE books out there. This book focuses on workflows – or recipes, as the author calls them – that will help MBSE practitioners and team leaders address practical situations that are part of deploying MBSE as part of an agile development process across the enterprise. Written by Dr. Bruce Powel Douglass, a world-renowned expert in MBSE, this book will take you through important systems engineering workflows and show you how they can be performed effectively with an agile and model-based approach. You’ll start with the key concepts of agile methods for systems engineering, but we won’t linger on the theory for too long. Each of the recipes will take you through initiating a project, defining stakeholder needs, defining and analyzing system requirements, designing system architecture, performing model-based engineering trade studies, all the way to handling systems specifications off to downstream engineering. By the end of this MBSE book, you’ll have learned how to implement critical systems engineering workflows and create verifiably correct systems engineering models.

Architecture 0

Architecture 0 is the set of strategic design optimization decisions for the system. Many different architectures can meet the same functional needs. What distinguishes them is their optimization criteria. One architecture may optimize worst case performance, while another may optimize extensibility and scalability, and yet another may optimize safety, all while meeting the same functional needs.

The Harmony process identifies five key views of architecture:

  • Subsystem and component view: This view focuses on the largest scale pieces of the system, as well as their organization, relations, responsibilities, and interfaces.
  • Concurrency and resource view: This view focuses on the concurrency units and management of resources within the system. Processes, tasks, threads, and the means for safely sharing resources across those boundaries are the primary concerns of this view.
  • Distribution view: This view focuses on how collaboration occurs between different...
