Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking the firmware update might be directly related to the satisfaction drop. Could you confirm when exactly the firmware update was rolled out and if it coincided with the start of the satisfaction decline?

Why it matters: Establishing a clear timeline helps determine if there's a direct causal relationship. Expected answer: The firmware update was released on [specific date], and the satisfaction decline began shortly after. Impact on approach: A strong correlation would focus our investigation on the firmware update itself.

• I'm curious about the nature of the satisfaction metric. Is this based on NPS scores, customer support tickets, or another measure? And has the measurement method remained consistent?

Why it matters: Understanding the metric helps validate its accuracy and relevance. Expected answer: The metric is based on [specific measure] and has remained consistent. Impact on approach: Knowing the metric's composition will guide our data analysis and hypothesis formation.

• Considering the scope, I'm wondering if this decline is uniform across all user segments or if it's more pronounced in specific groups. Do we have data on how different user segments are affected?

Why it matters: Identifying patterns in affected segments could point to specific issues or use cases. Expected answer: The decline is [uniform/varied] across segments, with [specific segment] showing the largest drop. Impact on approach: Segment-specific issues would require targeted solutions and prioritization.

• Given the technical nature of the update, I'm thinking about potential performance changes. Have there been any significant changes in network performance metrics (speed, latency, uptime) since the update?

Why it matters: Performance issues could directly impact user satisfaction. Expected answer: There have been [no changes/specific changes] in network performance metrics. Impact on approach: Significant performance changes would shift focus to technical optimizations.
