Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be a weekend-specific issue. Can you confirm if this drop was observed only during the weekend or if it persisted into the following week?

Why it matters: Understanding the duration helps determine if it's a temporary glitch or a more persistent problem. Expected answer: The issue was limited to the weekend. Impact on approach: If limited to the weekend, we'd focus on weekend-specific factors; if ongoing, we'd consider broader systemic issues.

• Given the magnitude of the drop, I'm wondering about recent changes. Were there any significant updates to the checkout process or related systems in the days leading up to this incident?

Why it matters: Recent changes are often the culprit in sudden performance drops. Expected answer: A minor UI update was pushed on Friday. Impact on approach: If changes were made, we'd prioritize investigating those specific updates.

• Considering user segments, I'm curious if this affected all users equally. Do we have data on whether this impacted new users differently from returning customers?

Why it matters: Different impacts on user segments could point to specific areas of the checkout process. Expected answer: The impact was more severe for new users. Impact on approach: If new users were more affected, we'd focus on onboarding and first-time user experience in the checkout process.

• Thinking about external factors, have there been any reported issues with payment gateways or other third-party services integrated into our checkout process?

Why it matters: Third-party service disruptions can significantly impact checkout conversion rates. Expected answer: No reported issues from payment partners. Impact on approach: If no external issues, we'd focus more on internal factors; otherwise, we'd coordinate with affected partners.
