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.

Defining designs

When considering the development of any system, there are three concepts that may be considered in the early stages of the life cycle:

  • Understanding the need: This involves identifying the needs of the system, such as the goals, capabilities, and requirements of the system. This was covered in Chapter 6, Needs and Requirements. This is typically carried out in the concept stage of the ISO 15288 life cycle.
  • Understanding the problem: This involves analyzing the needs of the system in order to understand the problem or problem domain. In systems engineering, this is addressed by context modeling and scenario modeling, which were also discussed in Chapter 6, Needs and Requirements. This is typically carried out in the concept stage of the ISO 15288 life cycle.
  • Understanding the solution: This is concerned with solving the problem that arises as a result of understanding the needs of the system. This is typically carried out in the development stage of...
