This document provides an introduction to complex system engineering. It defines what a system is, discusses system engineering and the system engineering process. It covers topics such as requirements, design, architecture, integration, verification and validation. The goal of system engineering is to design the right system to satisfy customer needs using an interdisciplinary approach.
