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.

Federating models for handoff

The systems engineering model is, at least abstractly, a single model. In practice, large systems engineering models may be split up into multiple projects (roughly, but not precisely, "models"), but that is done for convenience. Logically, it is a singular coherent model with the systems engineering data.

Downstream engineering is different in that many separate, independent models will be created. These models will interact with each other in specific and well-defined ways. A set of such independent, yet connected models is called a federation, and the process of creating the models and their linkages is called model federation.

One of the key ideas in model federation is the notion of a single source of truth. This concept means that while there may be multiple sources for engineering data, each specific datum is owned in a single, well-defined location known as the datum's authoritative source. When a value is needed, the authoritative...
