Welcome to Introduction to A Digital Business Primer, a thrilling new text on the fourth industrial revolution and its intersections with business, organizational strategy, and digital transformation and change. It has become practically axiomatic that technology is a pervasive and accelerating influence on organizations, with wide-reaching impacts on every level of management and business function, from product design and customer experience to HRM and finance. However, there are so many unknowns and underdeveloped areas of knowledge within the arenas of digitalization and the fourth industrial revolution. What do these things refer to in the first place? What really are the implications for organizational strategy – does strategy change fundamentally, or rather adapt traditional thinking and models to new realities? How do organizational effectively and correctly transform themselves to these forces, in order to thrive in our new realities? Therefore, this book addresses these questions in five parts comprising thirteen chapters. Part I contains a chapter giving an introduction to digitalization and digital business. Part II then expands on the major fourth industrial revolution (4IR) technologies in three chapters – Chapter 2 on foundational 4IR technologies, Chapter 3 on the ‘virtuous triangle’ on big data, IoT and AI, and Chapter 4 on other 4IR technologies. Part III unpacks specific topics on strategy in the digital age: Chapter 5 on disruption and strategy, Chapter 6 on exponentials, abundance, and convergence, Chapter 7 on business models, Chapter 8 on platform businesses, and Chapter 9 on exponential organizations. Part IV covers topics in digital transformation and change management. Chapter 10 discusses digital transformation and change, maturity, Chapter 11 covers digital maturity, Chapter 12 discusses organizational architecture, and Chapter 13 unpacks lean innovation. A Digital Business Primer is a smaller companion text to the upcoming Digital Business by the same authors, which provides an additional major section on strategy in the digital world as well as an expanded digital transformation and change section. Together, these texts are essential reading for our time, appropriate and important for managers and business owners, business students, consultants, 4IR experts, and others who are affected by the ongoing technological revolution of our era.
