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.

Work item prioritization

This recipe is about the prioritization of work items in a backlog. There is some confusion as to the meaning of the term priority. Priority is a ranking of when some task should be performed with respect to other tasks. There are a variety of factors that determine priority and different projects may weight such factors differently. The most common factors influencing priority are as follows:

  • Cost of delay: The cost of delaying the performance of the work item, which in turn is influenced by the following:

    a. Criticality: The importance associated with completing the work item

    b. Urgency: When the outcome or output of the work item completion is due

    c. Usefulness: The value to the outcome of the work item to the stakeholder

    d. Risk: How the completion of the work item affects the project risk

  • Opportunity enablement: How the completion of the work item will enable stakeholder opportunity
  • Cost: The cost or effort required to complete the work item...
