Definition: The term "DDM" (Digital Disruption Matrix) was first introduced in 2013 by David Brooks, a media analyst and author who focuses on topics related to technology and business. The concept of a DDM matrix refers to an analysis of how digital technologies are disrupting various industries. In the DDM matrix, each industry is represented by a "D" (Data), "M" (Marketing) or "S" (Social). The matrix then shows how these three components interact with one another and how they can affect different parts of the industry. For example, a business that relies heavily on social media for its marketing strategy may benefit from having a DDM matrix that includes both the digital footprint and the social dimension. The DDM matrix is considered to be one of the most influential tools in the field of digital disruption analysis, as it can help organizations understand how different aspects of their operations are being impacted by digital technologies. It also provides insights into how companies can improve their performance and adapt to the changing landscape of technology. Overall, the DDM matrix is a valuable tool for businesses that want to stay competitive and relevant in an increasingly digital world.
