This book introduces state-of-the-art concepts and methodologies on innovative systems approach that enables the grand design and implementation about Smarter World. This book also describes the shared view that the various heterogeneous social systems that make up Smarter World should be viewed as systems at an abstract level, and develop new developments in SoS and spiral systems through the cycle of analysis, synthesis and abduction. Several new concepts that integrate data-driven mechanism into traditional model-driven methodologies in systems approach are explained with practical applications. As such, it offers a valuable resource for systems engineers, system integrators, and researchers in related engineering fields, as well as government policymakers.
