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.

Modeling Verification and Validation

The modeling that has been introduced so far in this book has been concerned with the creation of several Views related to specifying and defining the System and that contribute to delivering the System successfully. Remember that the main aim of Systems Engineering is to deliver successful Systems.

Alongside these modeling activities, it is also important to be able to test that what we have produced is correct, and this is done in two main ways:

  • Verification: This helps us demonstrate that the System works. This was summed up, very famously, by Boehm by asking the question, have we built the System right?
  • Validation: This helps us demonstrate that the System actually does what it is supposed to – that it is fit for purpose. This was again summed up neatly by Boehm by asking the question, have we built the right System?

It is essential that the System can be both verified and validated, and it must be remembered...
