Clarifying Questions (3 minutes)

• Looking at the scope, I'm thinking this might be a recent issue. Has this 30% failure rate been consistent, or did it spike recently?

Why it matters: Helps determine if it's a new problem or an ongoing issue we've overlooked. Expected answer: It's a recent spike in the last month. Impact on approach: A sudden change would point us towards recent product updates or technical issues.

• Considering user segments, I'm wondering if this affects all types of accounts equally. Are we seeing any patterns in terms of account types (e.g., basic, standard, premium) or device types?

Why it matters: Identifies if the issue is universal or specific to certain user groups. Expected answer: The issue is more prevalent in standard and premium accounts. Impact on approach: Would focus our investigation on features or settings specific to these account types.

• Thinking about user behavior, I'm curious about the actual restriction bypass. Are kids actually accessing restricted content, or is the restriction just not visibly applied?

Why it matters: Distinguishes between a UI issue and an actual security breach. Expected answer: The restriction is visibly applied but can be easily bypassed. Impact on approach: Would shift focus to the authentication and restriction enforcement mechanisms.

• Considering recent changes, have there been any updates to the Kids profile feature or related systems in the past 3 months?

Why it matters: Helps identify if a recent change might have introduced the issue. Expected answer: Yes, there was an update to improve the user interface of Kids profiles. Impact on approach: Would prioritize investigating the recent update and its potential unintended consequences.
