Clarifying Questions (3 minutes)

• Considering the scale of the issue, I'm thinking this might be a recent development. Has this 45% failure rate been observed suddenly, or has it been gradually increasing over time?

Why it matters: Understanding the timeline helps identify potential triggers or changes that led to this issue. Expected answer: A sudden increase in failure rate. Impact on approach: A sudden change would point towards a recent update or external factor, while a gradual increase might indicate a systemic issue.

• Given the offline nature of the translation, I'm wondering about the device types affected. Are we seeing this issue across all device types and operating systems, or is it concentrated on specific platforms?

Why it matters: This information helps narrow down whether the problem is device-specific or a broader issue. Expected answer: The issue is present across multiple device types but may be more prevalent on certain platforms. Impact on approach: If device-specific, we'd focus on platform-related causes; if widespread, we'd look at the core offline translation technology.

• Considering user behavior, I'm curious about the types of translations being attempted. Are we seeing failures across all language pairs, or are certain languages or language directions more affected?

Why it matters: This could indicate issues with specific language models or data sets. Expected answer: Some language pairs are more affected than others. Impact on approach: We'd prioritize investigating the most affected language pairs and their associated models.

• Thinking about recent changes, have there been any updates to the offline translation model or the app itself in the past few weeks?

Why it matters: Recent updates are often the culprit in sudden performance changes. Expected answer: Yes, there was a recent update to the offline translation model. Impact on approach: We'd focus on changes introduced in the recent update and their potential impact on translation performance.
