• Looking at the timing, I'm thinking there might be seasonal factors at play. Has this 8% decrease been consistent across all quarters, or is it more pronounced in certain periods?

Why it matters: Seasonal patterns could indicate cyclical behavior rather than a persistent problem. Expected answer: The decrease is consistent across quarters. Impact on approach: If seasonal, we'd focus on year-over-year comparisons and cyclical strategies.

• Considering user segments, I'm curious about the distribution of the decrease. Is the 8% drop uniform across all prepaid user segments, or are certain groups more affected?

Why it matters: Identifying specific affected segments could pinpoint targeted issues. Expected answer: The decrease varies across segments, with younger users showing a larger drop. Impact on approach: We'd prioritize investigating and addressing issues specific to the most affected segments.

• Thinking about recent changes, have there been any significant alterations to the prepaid plan offerings or pricing structure in the past year?

Why it matters: Product changes could directly impact ARPU. Expected answer: Minor tweaks were made to some plans, but no major overhauls. Impact on approach: We'd analyze the impact of these changes and consider reverting or further optimizing them.

• Regarding competitive landscape, has there been any notable shift in competitor offerings or market dynamics in the prepaid space?

Why it matters: External market forces could be driving the ARPU decrease. Expected answer: A new competitor entered with aggressive pricing six months ago. Impact on approach: We'd focus on competitive analysis and potential repositioning strategies.

• Considering technical aspects, has there been any change in how ARPU is calculated or in the systems measuring it?

Why it matters: Ensures we're comparing apples to apples and not chasing a data anomaly. Expected answer: No changes in calculation or measurement systems. Impact on approach: If changes occurred, we'd need to recalibrate our analysis based on consistent metrics.
