How the Leader of MyRealTrip's Largest Organization, the T&A Division, Uses AI

The 8th installment of MyRealTrip's AI Champion series shows how Team Lead Choi Seung-mo of the T&A Division's Japan team transformed his team's work structure using AI.

The T&A Division is a large organization where sales, partnerships, planning, and operations are all intertwined, so the cost of confirmation and coordination needed to complete a single promotion kept growing. People were busy, but the time they could actually spend on areas that require human focus—like sales and strategy—kept shrinking.

Team Lead Choi saw this not as a staffing shortage but as a structural problem, and before asking his team to use AI, he first started applying AI to his own work. His starting point was the most repetitive task: the promotion results report.

First, he consolidated the scattered Google Sheets into a single structure and unified the KPI definitions to establish consistent data standards. Next, he connected BigQuery with the sheets so KPIs would update automatically, and used Apps Script and Clasp to reduce the recurring burden of data aggregation and deployment.

AI wasn't used as a tool to replace final judgment, but to generate draft reports based on the organized data. It was set up to produce drafts answering questions like the characteristics of performance, changes compared to before, and next actions, while keeping the structure where judgment and final decisions remained with humans.

The early outputs weren't perfect, but the standard wasn't completeness—it was whether it could be used right now. By accumulating human-edited results, output quality improved over time, and in the process, the team's questions shifted from "When does this need to be done by?" to "Why did it turn out this way, and what should we try next?" Ultimately, the core of this case wasn't technical proficiency, but the leader's attitude of trying things out first, accepting failure, and building the structure needed for the organization to move forward.
