• Looking at the timing, I'm thinking this could be a recent development. When exactly did you first notice this 30% drop in transaction volume?

Why it matters: Understanding the timeframe helps narrow down potential causes and correlate with any recent changes or events. Expected answer: The drop was noticed in the last 7-14 days. Impact on approach: A sudden drop would point towards a specific trigger event, while a gradual decline might indicate a broader trend or user behavior shift.

• Considering user segments, I'm wondering if this affects all user types equally. Have you noticed any differences in the drop across various user segments, such as age groups or frequency of use?

Why it matters: Identifying affected segments can help pinpoint whether the issue is universal or specific to certain user groups. Expected answer: The drop is more pronounced among younger users (18-35) and frequent users. Impact on approach: If specific segments are more affected, we'd focus on investigating factors unique to those groups.

• Given the significance of the drop, I'm curious about any recent product or system changes. Have there been any updates to the GrabPay system, user interface, or policies in the past month?

Why it matters: Recent changes could directly correlate with the drop in transaction volume. Expected answer: A minor UI update was rolled out two weeks ago, and a new fraud detection system was implemented. Impact on approach: This information would guide us to investigate these specific changes as potential root causes.

• Considering the competitive landscape, I'm wondering about any recent moves by competitors. Has there been any significant promotion or feature launch by other digital payment providers in Singapore recently?

Why it matters: Competitive actions could explain a shift in user behavior. Expected answer: A major competitor launched a cashback promotion last week. Impact on approach: If true, we'd need to assess our competitive positioning and consider short-term promotional strategies.
