Introduction
The increase in average response time for Brandwatch Vizia data visualizations from 2 seconds to 5 seconds this quarter is a critical issue that demands immediate attention. This performance degradation directly impacts user experience and could potentially affect customer retention and satisfaction. I'll approach this problem systematically, focusing on identifying the root cause, validating hypotheses, and developing both short-term fixes and long-term solutions.
This analysis follows a structured approach covering issue identification, hypothesis generation, validation, and solution development.

Clarifying Questions (3 minutes)
Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there have been updates. Impact on approach: If yes, we'll focus on recent changes; if no, we'll look at gradual degradation factors.
Why it matters: Helps narrow down the scope of the problem. Expected answer: It affects most users but may vary by visualization complexity. Impact on approach: If segmented, we'll investigate specific user groups or data types.
Why it matters: Data volume directly impacts processing time. Expected answer: There's been a moderate increase in data volume. Impact on approach: If yes, we'll focus on data processing optimizations; if no, we'll look at other factors.
Why it matters: Infrastructure problems can cause widespread performance issues. Expected answer: No major infrastructure issues reported. Impact on approach: If yes, we'll prioritize infrastructure fixes; if no, we'll focus on application-level optimizations.
