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 concepts

This section will follow the same structure as Chapter 4, Life Cycles, by introducing and discussing process concepts and developing an ontology that will form part of the broader MBSE ontology.

The first few concepts that must be understood are shown in the following figure:

Figure 5.1 – An ontology definition view for process concepts

The diagram in Figure 5.1 shows the initial ontology definition view for process concepts, visualized using a SysML block definition diagram.

The main concept in this view is the process, which describes an approach to doing something or achieving an aim of some description. As can be seen in the preceding figure, Process is made up of three main elements:

  • Activities: An activity describes a behavioral step that must be performed in order to execute the process. A typical process will be made up of a number of these activities, each of which will have inputs, which are consumed, and...
