Recent advances in AI and data utilization have increased the importance of understanding customers through "relationships and behaviors" rather than "attributes" across all industries. This section reviews changes in customer experience accompanying technological innovation since the 1990s and organizes the foundations of customer understanding in the AI era (Figure 1).
Beginning in the late 1990s, retailers launched e-commerce businesses, and platforms such as Amazon and Rakuten began gaining prominence. Customers started searching for products within these platforms, while companies were required to establish inventory management, order fulfillment management, and logistics reforms to handle orders received through Amazon and Rakuten e-commerce platforms.
Since the late 2010s, the growth of e-commerce packages and SaaS (software as a service)-based e-commerce platforms has accelerated the D2C (direct-to-consumer) trend, with companies establishing their own e-commerce sites. Customers became able to receive product recommendations and email newsletters based on purchase and browsing histories on company-operated e-commerce sites, while companies were required to introduce their own e-commerce platforms and reform CRM (customer relationship management) operations to enable these customer experiences. These efforts accelerated during the COVID-19 pandemic as restrictions on outings reduced in-store purchases and made customers less visible to companies.
More recently, customer experience design has increasingly utilized not only conventional data such as personal information and purchase histories, but also more real-time and diverse data including location information, behavioral logs, and content viewing histories.
In particular, advances in generative AI have made it possible to optimize recommendations and communications in real time according to each customer's interests and behaviors. As a result, experiences tailored at the "individual customer" level, rather than at the segment level, are becoming a reality.
At the same time, advances in purchasing experiences linked to live streaming and social networking services have made entertainment-driven consumption mainstream, where customers not only purchase products but also make decisions while enjoying content.
In this way, technological innovations including AI are not only improving efficiency in customer experiences but also evolving them into experiences that increase customer enthusiasm. Companies are therefore required to move beyond thinking based on traditional sales channels and redesign their relationships with customers themselves. To realize these customer experiences, it is essential to continuously understand customer behaviors and levels of engagement while deepening relationships. For this reason, the importance of D2F, through which companies connect directly with customers, continues to grow.
Looking ahead, these changes are expected to accelerate further, with customer experiences evolving beyond simple optimization to become experiences that generate enthusiasm and empathy.
