Agile Model-Based Systems Engineering Cookbook Second Edition - Second Edition

By: Dr. Bruce Powel Douglass

Overview of this book

Agile MBSE can help organizations manage change while ensuring system correctness and meeting customers’ needs. But deployment challenges have changed since our first edition. The Agile Model-Based Systems Engineering Cookbook’s second edition focuses on workflows – or recipes – 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. In this 2nd edition, the Cameo MagicDraw Systems Modeler tool – the most popular tool for MBSE – is used in examples (models are downloadable by readers). Written by a world-renowned expert in MBSE, this book will take you through systems engineering workflows in the Cameo Systems Modeler SysML modeling tool and show you how they can be used with an agile and model-based approach. You’ll start with the key concepts of agile methods for systems engineering. Next, each recipe will take you through initiating a project, outlining stakeholder needs, defining and analyzing system requirements, specifying 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 learn how to implement systems engineering workflows and create systems engineering models.

Effective Reviews and Walkthroughs

At the beginning of this chapter, I talked about reviews being the easiest but weakest form of model verification. This shouldn’t be construed to mean that I don’t believe reviews have value. Properly applied, reviews are a very useful adjunct to other, more rigorous forms of verification. Reviews can contribute to both syntactic (“compliance in form”) and syntactic (“compliance in meaning”) verification. They are relatively easy to perform and can provide input that is otherwise difficult to obtain.

Syntactic reviews, performed by quality assurance personnel, demonstrate compliance of the model to the project modeling guidelines, including organization of the model, the presence of required elements and views, the structuring of those views, compliance with naming conventions, and more.

Semantic reviews are performed by Subject Matter Experts (SMEs). Some of the questions such reviews can address include:

  • Does...
