Overview of this book

Systems engineering helps in developing and describing complex systems. Written by an internationally-recognized systems engineering expert, this updated edition provides insight into elements to consider when designing a complex system that is robust and successful. The latest edition covers the new approaches of Model-Based Systems Engineering (MBSE) and its deployment techniques using the Trinity approach. You will learn about the system engineering life cycle and processes to implement. Effective systems can be built only when the system is designed with close attention to detail, meaning each aspect of the system is recognized and understood before the system is built. The book explains in great detail, different system models and visualization techniques, with a focus on SysML, to help you visualize a system in the design phase. You will also learn various verification and validation techniques to ensure your system design is ready to be implemented. The book ends with key management processes, systems engineering best practices, and guidelines, with a new section on effective approaches based on the author’s impressive 30 years of experience in the field. By the end of this systems engineering book, you'll be able to apply modern model-based systems engineering techniques to your own systems and projects.

Visualizing Needs using different SysML diagrams

The previous section defined the concepts associated with Needs in the form of the Needs Ontology. This section looks at each of these in more detail and shows how Needs may be realized using a number of different Views, each of which will be visualized using the SysML notation.

Visualizing Source Elements

This section discusses the importance of defining Source Elements and introduces the Source Element View, which is used to visualize these Source Elements. It is important that all Needs have a provenance, and Source Elements allow us to identify exactly where each Need has come from. There are five basic reasons why we need to identify these Source Elements, which are as follows:

  • To identify the origin of all the Needs that are defined for a System: This is something that is often overlooked or neglected altogether, but this is important for a number of reasons.
  • To demonstrate the provenance of all Needs...
