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.

Architectural trade studies

Trade studies are specifically concerned with the merit-based selection of approach or technology based on important concerns specific to the system development, system environment, or stakeholder needs. At a very fundamental level, trade studies are about making design choices to optimize important properties of the system at the expense of properties deemed less critical. To effectively perform trade studies, it is important to identify the things that can be optimized, the aspects subject to optimization, the MoE, and a set of alternatives to be evaluated.

Purpose

The purpose of performing an architectural trade study is to select an optimal design solution from a set of alternatives.

Inputs and preconditions

The inputs to this recipe are:

  1. Functionality of concern, scoped as a set of requirements and/or use cases
  2. Design options capable of achieving that functionality

Outputs and postconditions
