• Looking at the timing, I'm thinking there might be a recent product change. Has there been any significant update to the Money Transfer service in the last month?

Why it matters: Recent changes could directly impact user behavior. Expected answer: Yes, a UI redesign was implemented three weeks ago. Impact on approach: If confirmed, I'd focus on usability issues in the new design.

Why it matters: Ensures we're addressing a real issue, not a measurement anomaly. Expected answer: No changes in tracking methods. Impact on approach: If there were changes, I'd investigate data consistency first.

• Given the magnitude of the decline, I'm curious about user segments. Are we seeing this 25% drop across all user demographics, or is it concentrated in specific groups?

Why it matters: Helps narrow down potential causes and target solutions. Expected answer: The decline is more pronounced in older users. Impact on approach: I'd focus on age-specific usability or marketing issues if confirmed.

• Considering potential external factors, have there been any significant competitor actions or market changes in the past month?

Why it matters: External factors could explain the decline without internal issues. Expected answer: A major competitor launched a promotional campaign two weeks ago. Impact on approach: If confirmed, I'd analyze our competitive positioning and marketing strategy.
