Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking the update might be directly related. Could you provide more details on when exactly the error rate increase was first noticed relative to the update?

Why it matters: This helps establish a clear timeline and potential correlation. Expected answer: The error rate increase was noticed within 24-48 hours of the update. Impact on approach: A close temporal relationship would strengthen the focus on update-related issues.

• Considering user segments, I'm wondering if this is affecting all users equally. Have you noticed any patterns in terms of user demographics or device types experiencing higher error rates?

Why it matters: This could point to specific user-related or technical factors. Expected answer: There's a higher error rate among users with older smartphone models. Impact on approach: This would shift focus to compatibility issues or device-specific optimizations.

• Given the nature of medication adherence tracking, I'm curious about the specific type of errors being reported. Are these data synchronization issues, false positives in adherence tracking, or something else?

Why it matters: Different error types suggest different root causes and solutions. Expected answer: The errors are primarily related to false negatives in adherence tracking. Impact on approach: This would focus our investigation on the adherence detection algorithm and related components.

• Thinking about the update process, I'm wondering about the rollout strategy. Was this a phased rollout or a universal update?

Why it matters: This could help identify if the issue is universal or limited to certain deployment phases. Expected answer: It was a phased rollout, with 20% of users updated each day over five days. Impact on approach: This would allow for comparison between different user groups and potentially isolate the problem.
