Clarifying Questions (3 minutes)

• Looking at the failure rate, I'm wondering about the scope. Is this 30% failure rate consistent across all Kindle devices and apps, or is it specific to certain versions?

Why it matters: Helps narrow down potential hardware or software-specific issues. Expected answer: Varies across devices/apps. Impact on approach: Focus on specific platforms or a system-wide investigation.

• Considering user behavior, have we seen any changes in highlight frequency or length recently?

Why it matters: Could indicate user-driven factors or changes in content. Expected answer: No significant changes observed. Impact on approach: Shift focus to technical or system-related causes.

• Thinking about recent updates, has there been any change to the highlighting feature or related backend systems in the past month?

Why it matters: Identifies potential correlation with recent changes. Expected answer: Minor update to sync algorithm. Impact on approach: Investigate the update's impact on highlight saving.

• Regarding data integrity, are we confident in the accuracy of the 30% failure rate, and how is this metric being tracked?

Why it matters: Ensures we're addressing a real issue, not a measurement error. Expected answer: Metric is accurate, tracked through server-side logs. Impact on approach: Proceed with root cause analysis, focusing on server-side issues.
