■Session Contents (Partial Excerpt)

1. LIFULL Co., Ltd. | Fostering a Data-Driven Culture ~Roadmap for Product Analytics Implementation~

In the first part, a panel discussion was held with Mr. Ryotori, Ms. Mizuno, and Mr. Inoue from LIFULL Co., Ltd. as panelists, and Mr. Asano from DearOne as moderator.

The discussion covered quantitative achievements such as improvements in "market learning frequency," "measure success rate," and "generated CVs" through Amplitude implementation, as well as changes in organizational culture from output-oriented to outcome-oriented.

The session was packed with reproducible knowledge, including the process of establishing Amplitude as an "organizational culture" beyond just a tool.

2. GLOBIS Corporation | PM's "Self-Sufficient" Growth Techniques that Doubled CTR by 2-3 Times with Zero Engineer Effort

In the second part, a cross-talk format with Mr. Shirahama from GLOBIS Corporation and Mr. Sugimoto and Mr. Ichiki from DearOne delved into the PM's problem-solving process utilizing Amplitude's "Guide & Survey*" function.

Facing the PM-specific challenge of "inability to quickly iterate PDCA due to tool and data fragmentation," they introduced a case study where the implementation of Guide & Survey reduced the measure lead time to one-tenth and increased CTR by 2-3 times. They elaborated on specific analysis methods in Amplitude and the metrics and data to focus on.

*Guide & Survey function: A function that displays messages at optimal timings based on user behavior data and collects opinions through surveys.
