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.

Deployment architecture I – allocation to engineering facets

The Federating models for handoff recipe created a set of models, a Shared Model and a separate model per subsystem. The current recipe creates what is called the deployment architecture and allocates subsystem features and requirements to different engineering disciplines. Once that is done, the software, electronic, and mechanical design can begin, post-handoff.

Deployment architecture

Chapter 3, Developing System Architectures, began with a discussion of the Five Critical Views of Architecture. One of these, the deployment architecture, is the focus of this and the next recipes. The deployment architecture is based on the notion of facets. A facet is the contribution to a design that comes from a single engineering discipline (Figure 4.22). A typical subsystem integrates a number of different facets, the output from engineering in disciplines including the following:

  • Electronics: Power, motor, analog...
