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.

Process modeling

This section builds on the previous discussion on process concepts and shows how they are applied to process modeling.

Defining the process context

It was mentioned in the previous section that understanding why a process, or a set of processes, is required is essential. The concept of a context has been mentioned on a number of occasions so far in this book. In this section, an example will be provided for the first time with a high-level explanation, as a detailed description of contexts will be provided in the next chapter.

The example of the car will be revisited for the process modeling views that will be presented, the first of which is shown in the following figure:

Figure 5.4 – A process context view showing the rationale for the process set

The preceding figure contains a process context view that shows the rationale for a set of processes, visualized using a SysML use case diagram. This is the first time that a use...
