''The Information Society'' that we live in today is largely driven by the products and services that either contain software as a core element, or are themselves software. At the very least, it is likely that most of those same products and services were manufactured with the help of some type of sophisticated software applications. Because of that, as well as the stresses of navigating through a truly global economy, the skills of software developers and engineers are being pushed to the limit. As a result of those growing complexities, it has become imperative that software engineers and developers understand the methods, tools and techniques for identifying, documenting and validating the requirements of complex systems. In turn, more emphasis is now being placed on Requirements Engineering and the role it plays in today’s Information Society. Because of that, Requirements Engineering has now transcended its traditional role within software development and become an integral part of product and systems engineering. Requirements Engineering for Socio-Technical Systems provides a comprehensive view of many of the system requirements for some of the hottest areas in development today. In addition, readers with understanding of human factors and social issues embedded within the development of socio-technical systems.
