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.

Effective reviews and walk-throughs

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 very useful as an adjunct to other, more rigorous forms of verification. Reviews can contribute to both syntactic and syntactic 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 the compliance of the model to the project modeling guidelines, including the 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, for short). Some of the questions such reviews can address include the following:

  • Does the model appropriately...
