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.

Summary

This chapter has introduced two example methodologies: SAFe and OOSEM. Both of them may be used as part of a wider systems engineering endeavor, but they have quite different purposes.

Each methodology was modeled using ontologies.

Finally, each methodology was mapped to the MBSE in a slide diagram that has been referred to throughout this book. It should be clear that both methodologies fit in with MBSE and can be used to satisfy the different aspects of MBSE in a slide.

By relating these existing methodologies to what we have learned so far in this book, it has been illustrated how we can use MBSE to incorporate any approach into a wider systems engineering initiative.

In the next chapter, we will understand the management processes and associated techniques to be considered and implemented.
