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.

Functional analysis with state machines

Sometimes beginning with the state machine is the best approach to do use case analysis. This is particularly true when the use case is obviously “modal” in nature with different operational modes. This approach generally requires systems engineers who are very comfortable with state machines. The recipe is much like the previous use case analyses and can be used instead; the output is basically the same for all three of these recipes.

The primary differences are that no activity diagram is created and the sequence diagrams are created from the executing use case state behavior.

Purpose

The purpose of the recipe is to create a set of high-quality requirements by identifying and characterizing the key system functions performed by the system during the execution of the use case capability. This recipe is particularly effective when the use case is clearly modal in nature and the system engineers are highly skilled...
