Information systems research (IS) is an exciting multidisciplinary area that links the rapidly changing technology of information (or communications and information technology, ICT) to the business and social environment. Lately, the discourse surrounding information and systems has leaped into the consciousness of the public in unprecedented ways through the rise of social media, the Internet of Things (IoT), 'fake news' and the weaponization of information, to name a few. Unfortunately, it has been felt that these developments are overtaking the ability of the IS field to address them, in part, because the field itself lacks its own native theories. It is well known that the IS field undertakes its research using theories from its 'reference disciplines' such as management, social psychology, economics, communication and computer science, but what this book offers is a clarification and implementation of the discipline's own foundational theory.
