Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be a recent development. When exactly did we start noticing this increase in failed transactions?

Why it matters: Pinpointing the timeframe helps correlate the issue with potential changes or events. Expected answer: Within the last week or two. Impact on approach: A sudden spike would suggest a recent change or external event, while a gradual increase might indicate a systemic issue.

• Considering the specificity to mobile devices, I'm wondering about the distribution across different mobile platforms. Are we seeing this issue equally on iOS and Android, or is it more prevalent on one platform?

Why it matters: Platform-specific issues could narrow down the potential causes significantly. Expected answer: The issue is more pronounced on Android devices. Impact on approach: If platform-specific, we'd focus on Android-related changes or issues; if universal, we'd look at cross-platform factors.

• Given the nature of checkout processes, I'm curious about the stage at which these failures are occurring. At what point in the checkout flow are we seeing the highest failure rate?

Why it matters: Different stages of the checkout process involve different systems and potential failure points. Expected answer: The failures are primarily occurring during the payment processing step. Impact on approach: This would focus our investigation on payment gateway integrations and transaction processing systems.

• Considering potential recent changes, have we rolled out any updates to the Bolt Checkout system or related components in the past month?

Why it matters: Recent changes are often correlated with sudden performance shifts. Expected answer: A minor update to the payment processing module was deployed two weeks ago. Impact on approach: This would make the recent update a prime suspect for investigation.
