The global business community faces increasingly complex challenges that cannot be met by stand-alone systems. This has led to the development of mega-systems: large-scale complex systems that provide a level of functionality not achieved by their individual components. This book focuses on the engineering of this class of systems, a process that demands consideration of increasing program scale and the rapid change of underlying technologies. The text offers a vocabulary and a framework to explore issues relevant to what makes mega-systems different from traditional ones. This framework results in the development of a model that can be used to select appropriate processes, tools, and techniques. .
