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.

Chapter 4: Handoff to Downstream Engineering

The purposes of the Handoff to Downstream Engineering recipes are as follows:

  • To refine the system engineering data to a form that's usable by downstream engineers
  • To create separate models to hold the prepared engineering data in a convenient organizational format (known as model federation)
  • For each subsystem to work with downstream engineering teams to create a deployment architecture and allocate systems engineering data to that architecture

It is crucial to understand that the handoff is a process and not an event. There is a certain amount of work to do that is not entirely straightforward in order to achieve the preceding objectives. As with other activities in the Harmony MBSE process, this can be done once, but it is recommended to be implemented many times, in an iterative, incremental fashion. It isn't necessarily difficult work, but it is crucial work in terms of the project being successful....
