This book brings an integrated perspective to several major current themes in the engineering of technological and business systems. Part I begins with an introduction that explains and applies ideas and practices from the fields of Systems Engineering, Systems Thinking, User Centric Design and Artificial Intelligence/Machine Learning. Part II shows how to use the best techniques of systems design and model-based systems engineering in a highly visual way, providing many benefits to the practice of systems engineering. These include better communication within the project or program engineering and development team, clearer conceptualization and understanding of the system and its behavior and architecture, and faster overall development cycle time. Part III discusses how to make human activity systems more intelligent by introducing new technology and changing how humans act to improve overall performance.
