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.

The pattern-driven architecture

A design pattern is a generalized solution to commonly occurring problems. Let's break this down.

First, a design pattern captures a design solution in a general way. That is, the aspects of the design that are unique to the specific problem being solved are abstracted away, leaving the generally necessary structures, roles, and behaviors as-is. The process of identifying the underlying conceptual solution is known as pattern mining. This discovered abstracted solution can now be reapplied to a different design context, a process known as pattern instantiation. Furthermore, while each design context has unique aspects, design patterns are appropriate for problems or concerns that reappear in many systems designs.

Note

Please refer to Design Patterns for Embedded Systems in C, by Bruce Douglass, Ph.D. 2014, for more information.

To help you work with design patterns, you should keep two fundamental truths in mind:

  • Design is all...
