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.

Managing Model Work Items

There are many ways to manage to do items or work items in a backlog. This recipe is one specific way to simply and easily manage work items within a model. I’ve found this an effective way to track and enact changes in models on projects.

Purpose

The purpose of this recipe is to allow model authors to track, manage, and enact work items for a model.

Inputs and preconditions

The input for this recipe is an existing model that has work to be performed on its elements.

Outputs and postconditions

The primary output is an updated model that contains not only the changes made but also a record of changes, along with their priority and status.

How to do it

Figure 5.44 shows the workflow for this recipe.

There are two flows within the recipe. The first adds new work items and assigns their properties, while the second resolves the work items:
