About the session in which XICA will be speaking
Amidst rising raw material costs and the ongoing headwinds of the "Japanese tea crisis," the top-selling brand, "Oi Ocha," is shifting from a defensive strategy to an offensive, data-driven one.
In this session, we welcome Mr. Shida, Executive Officer and Head of Marketing at Ito En Co., Ltd., to reveal the secrets behind the "evolution of decision-making" required in the age of AI. We will unravel the true drivers that drive customer loyalty for "Oi Ocha" and how they create a "winning scenario" that anticipates inflation and market changes through dialogue with AI. We will explore Ito En's challenge to elevate decision-making based on solid evidence into "organizational knowledge" in order to consistently deliver marketing with a tangible feel.
In the age of AI, competitive advantage will be determined not by technology, but by "human decision-making" and its assetization. This book delves deeply into the essence of how marketers can thrive in this era of inflation through the combined power of AI and data science.
