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.

Organizing your models

Packages are the principal mechanism for organizing models. In fact, a model is just a kind of package in the underlying SysML metamodel. Different models used for different purposes are likely to be organized in different ways. This recipe focuses on models for systems engineering to specifically support requirements capture, use case and requirements analysis, architectural trade studies, architectural design, and the handoff of relevant systems model data to the subsystem teams. In this recipe, we create not only the systems model, but the federation of models used in systems engineering.


Good organization is surprisingly important. The reasons for this include the following:

  • Group information to facilitate access and use.
  • Support concurrent model use by different team members performing different tasks.
  • Serve as the basis for configuration management.
  • Allow for relevant portions of models to be effectively reused.
  • Support...
