We have had a front row seat over the past three decades to how data, analytics, and now, AI, can transform businesses. As a Chief Data and Analytics Officer with AI responsibility for two Fortune 150 companies, as an author of groundbreaking books on competing with analytics and AI in business, and as a participant and advisor on data, analytics, and AI leadership to Fortune 1000 companies, we regularly counsel leading organizations on how they must structure their executive leadership to achieve the maximum business benefit possible from these tools. So, based on our collective first-hand experience, our research and survey data, and our advisory roles with these organizations, we can state with confidence that it almost always makes the most sense to have a single leader responsible for data, analytics, and AI. While many organizations currently have several C-level tech executives , we believe that a proliferation of roles is unnecessary and ultimately unproductive.
