Highly complex problem domains exist and are on the rise as we enter an Age of Interactions and Complexity. Our current world has been characterized by the plethora and ubiquity of information and global interconnections that link events and decisions to outcomes and effects that are often unpredictable and result in severe unforeseen and unintended consequences. Technological advances such as computers, the internet, Big Data, social media, artificial intelligence, and communication networks have expanded complex problem spaces. However, these same technologies present an opportunity to engineer a complex adaptive system of systems solution to address these challenging problems. This research project embarked on a classic grounded theory approach to study a number of knowledge domains and engineering processes, allowing a conceptual theory to emerge that offers an engineering solution to address highly complex problems. The project resulted in the emergence of a theory for a new class of engineered CASoS solutions. This paper details the classic grounded theory approach taken to conduct the research
