• Looking at the timing, I'm thinking there might be a recent change in our credit model. Has there been any update to our credit decisioning algorithm in the past month?

Why it matters: Algorithm changes could directly impact approval rates. Expected answer: Yes, there was a minor update. Impact on approach: If yes, we'd focus on validating the algorithm's performance.

• Considering user segments, I'm curious if this drop is uniform across all user groups. Are we seeing any particular demographic or credit score range more affected than others?

Why it matters: Helps identify if the issue is systemic or specific to certain user segments. Expected answer: The drop is more pronounced in the 600-650 credit score range. Impact on approach: If segmented, we'd investigate factors specific to the affected group.

• Given the significance of the drop, I'm wondering about any changes in our data sources. Have we switched or lost any credit data providers recently?

Why it matters: Data quality and completeness are crucial for accurate credit decisioning. Expected answer: No changes in data providers, but there was a brief outage with one provider. Impact on approach: If there were changes or issues, we'd focus on data integrity and completeness.

• Considering external factors, I'm thinking about potential market changes. Have we seen any significant shifts in the competitive landscape or economic indicators in the past month?

Why it matters: External factors could influence credit-worthiness or risk appetite. Expected answer: No major market shifts, but a competitor launched a more aggressive offer. Impact on approach: If external factors are at play, we'd need to reassess our competitive positioning.
