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.

Summary

In this chapter, the concept of Needs has been explored and the modeling associated with the different concepts covered has been discussed.

Initially, the importance of the concept of Needs and the different types of Needs, such as Requirements and Capabilities, was discussed. This led to understanding how to analyze Needs in two ways: by describing each Need using text-based properties and descriptions, and by gaining a true understanding of the underlying Needs by exploring the Contexts of each Need.

Context was introduced as one of the single most important aspects of Needs modeling and, in order to establish this understanding, how important it is to understand the Stakeholders that have an interest in the System. Each of these Stakeholders has the potential to interpret each Need in a different way from all other Stakeholders, which is known as a modeling Use Case.

Each Use Case, and therefore its related Need Descriptions, must be validated, and two ways...
