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 the framework

The views that have been created so far represent the center part of the MBSE diagram that was discussed in detail in Chapter 2, Model-Based Systems Engineering. Each of the views has been visualized using SysML, representing the right-hand side of the MBSE diagram. These views come together to form the overall model, but it is essential that these views are all consistent, otherwise they are not views but pictures! This is where the left-hand side of the MBSE diagram comes into play, as it is important that the definition of all of the views is captured in the framework. The framework comprises the ontology and a set of viewpoints; therefore, it is now time to make sure that these viewpoints are defined thoroughly and correctly, which is the aim of this section.

Defining the viewpoints in the framework

It was discussed in Chapter 2, Model-Based Systems Engineering, that it is necessary to ask a number of questions of each view to ensure that it is a valid...
