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.

Modeling verification and validation

It should be clear by now that verification and validation are important to delivering a successful system and, therefore, are essential parts of MBSE. In this section, we shall consider how modeling techniques may be applied to visualize the different aspects of testing and verification and validation.

One of the major advantages of modeling compared to a model-based approach comes into play now, as it is possible to reuse many of the views that have been generated so far as part of systems development for testing purposes. The more views that can be reused, then the more value that is added to the overall project as a direct result of modeling.

There are also other benefits to reusing existing views. One such advantage is that by using the same views that were used to develop the system, it is guaranteed that all of the information that is being used for the testing activities will be consistent, as it is using the same model. Remember that...
