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 life cycle models

Life cycles are defined by identifying a set of stages that describe the evolution of an entity. A life cycle is a structural construct. A life cycle model, on the other hand, is a behavioral construct that describes the execution of a life cycle, specifically the order of execution of the stages.

In terms of visualizing the various life cycle models, as the emphasis is on the order of the execution of the stages that comprise the life cycle, a SysML sequence diagram will be used. This is good for the consistency of the overall model but can lead to diagrams that differ in appearance compared to some of the traditional visualizations of life cycle models. This is because most life cycle models are visualized using non-standard, ad hoc notations, which leads to a set of very different-looking and difficult-to-compare diagrams. This illustrates one of the benefits of using a standard notation, such as SysML, as all of the different life cycle models may...
