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.

Complying with best-practice processes

The techniques for applying model-based techniques to verification and validation that have been introduced and discussed so far in this chapter may be used to comply with international best practice – in this case, ISO 15288 – software and systems engineering life cycle processes.

The two processes that are of interest are both taken from the technical process group and, unsurprisingly, are the Verification Process and the Validation Process. Each of these will be discussed in the following two sections.

Complying with the ISO 15288 Verification Process

The ISO 15288 process that is relevant for verification is the Verification Process. This has been captured and modeled using the approach described in Chapter 5, Systems Engineering Processes. The process content view for this process is shown in the following figure:
