Introduction
The sudden spike in average response time for chat support in Zendesk Chat since the latest software update is a critical issue that demands immediate attention. This problem directly impacts customer satisfaction and support efficiency, potentially leading to negative business outcomes. To address this, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both short-term fixes and long-term implications.
My analysis will follow a structured framework, covering issue identification, hypothesis generation, validation, and solution development. This approach ensures we thoroughly examine all potential factors contributing to the increased response time and develop a comprehensive plan to address the problem.

Clarifying Questions (3 minutes)
Why it matters: Establishing a clear timeline helps pinpoint potential causes. Expected answer: The update was deployed X days ago, aligning with the observed spike. Impact on approach: A close correlation would focus our investigation on the update itself.
Why it matters: Identifying affected segments can reveal specific vulnerabilities or bugs. Expected answer: The issue is more pronounced for mobile users or in certain regions. Impact on approach: Segmented data would help prioritize specific areas for investigation and resolution.
Why it matters: Changes in demand could explain longer response times independent of the update. Expected answer: Chat volume and complexity have remained relatively stable. Impact on approach: If stable, we'd focus more on system performance rather than capacity issues.
Why it matters: Human factors could contribute to or exacerbate technical issues. Expected answer: No significant changes in support team structure or processes. Impact on approach: If confirmed, we'd prioritize technical and system-related hypotheses.
Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes in metric definition or measurement. Impact on approach: Confirmation would validate the observed spike as a real issue rather than a measurement artifact.
