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.

Chapter 6: Needs and Requirements

This chapter focuses on introducing one of the most important techniques associated with MBSE, that of modeling needs and requirements.

Understanding needs is crucial to the success of any system as they provide the definition of all aspects of the system, such as the intended use, performance, function, form, and intent of the system.

Without understanding the needs of a system, it is impossible to say whether the delivered system is fit for purpose. This is because the purpose of that system is not known, as it is the needs that describe its purpose. Therefore, it is crucial that all needs are well defined and also that they are well understood by all of the stakeholders of the system. This is important as different stakeholders may interpret these need statements in different ways, depending on their context. Indeed, the topic of context will be described in detail as it is one of the most important aspects that must be clearly specified...
