Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent system update. Has there been any significant change to the audience targeting system in the last month?

Why it matters: System changes often lead to unexpected behavior. Expected answer: Yes, there was a recent update. Impact on approach: If yes, we'd focus on the update's impact; if no, we'd look at other factors.

• Considering the scale of the increase, I'm wondering about data volume. Has there been a sudden spike in the amount of data being processed?

Why it matters: Increased data volume could explain higher costs. Expected answer: There's been a 15% increase in data volume. Impact on approach: If yes, we'd investigate data sources; if no, we'd look at processing efficiency.

• Given the nature of audience targeting, I'm curious about changes in user behavior. Have we seen any shifts in user engagement patterns recently?

Why it matters: User behavior changes could affect data processing needs. Expected answer: No significant changes observed. Impact on approach: If yes, we'd analyze new patterns; if no, we'd focus on internal factors.

• Thinking about system health, I'm concerned about potential infrastructure issues. Have there been any reported system errors or performance degradation?

Why it matters: Technical issues could lead to inefficient data processing. Expected answer: Some minor latency issues reported. Impact on approach: If yes, we'd prioritize technical investigation; if no, we'd look at other areas.
