Systems Engineering Demystified

By: Jon Holt

Overview of this book

Systems engineering helps us to understand, specify, and develop complex systems, and is applied across a wide set of disciplines. As systems and their associated problems become increasingly complex in this evermore connected world, the need for more rigorous, demonstrable, and repeatable techniques also increases. Written by Professor Jon Holt – an internationally recognized systems engineering expert – this book provides a blend of technical and business aspects you need to understand in order to develop successful systems. You'll start with systems engineering basics and understand the complexity, communication, and different stakeholders' views of the system. The book then covers essential aspects of model-based systems engineering, systems, life cycles, and processes, along with techniques to develop systems. Moving on, you'll explore system models and visualization techniques, focusing on the SysML, and discover how solutions can be defined by developing effective system design, verification, and validation techniques. The book concludes by taking you through key management processes and systems engineering best practices and guidelines. By the end of this systems engineering book, you'll be able to confidently apply modern model-based systems engineering techniques to your own systems and projects.

Self-assessment tasks

  1. The concept of a concern was introduced as a need that relates specifically to a framework or viewpoint definition. Revisit Figure 6.6 and add on the concept of concern.
  2. Consider a set of stakeholders that is specific to your organization and capture these in a Context Definition View.
  3. Choose a single need that relates to any project that you are familiar with and describe it using text by creating a Need Description View.
  4. Based on your answers to questions 1 and 2, take your need description and consider it from three or four different stakeholders' points of view. For each, create a Need Context View.
  5. Choose any use case from the Need Context Views and define some validation views. Try out performance-based scenarios and operational scenarios. Now compare and contrast each scenario.
  6. There is an inconsistency in Figure 6.31 as an ontology relationship has been omitted from the diagram. Check each ontology element and its relationships...
